2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets – Complete Product Guide
The 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets are precision engine components designed specifically for the Yamaha YZ450F motocross bike models from 2014 through 2017. These shim buckets are critical parts within the cylinder head assembly that ensure correct valve clearance, reliable performance, and long‑lasting engine durability. Whether you’re rebuilding the top end or replacing worn valve train parts, quality shim buckets like this set help maintain optimal engine performance.
What Are 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets?
The 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets refer to a set of small, cylindrical components that sit between the camshaft lobe and the valve stem tip within the cylinder head of the Yamaha YZ450F four‑stroke engine. Their main purpose is to fine‑tune and maintain the correct valve clearance or “valve lash” — the small gap that allows the valve to open and close properly.
Because valve clearance affects engine performance, heat control, and wear patterns, these shim buckets must be accurately sized and installed. The 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets are engineered to meet the OEM specifications of the Yamaha YZ450F for these model years, ensuring reliable valve actuation and extended service life.

Comparing with Related Products
OEM Yamaha Valve Shim Kit
The official Yamaha parts kit provides exact OEM quality but at a higher price point. The 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets are an aftermarket alternative that offers similar tolerances with strong material quality, often at better value.
Universal Valve Shim Buckets
Generic or universal shims may not match the precise dimensions needed for the Yamaha YZ450F top end, which can lead to inconsistent valve clearances. The 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets are tailored specifically for these YZ450F model years.
Performance/Race Valve Kits
Some high‑end valve shim kits include lightweight or hard‑anodized components designed for race engines. While these can perform well, they may require closer tuning and monitoring.

The 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets I got from femotorsport ended months of frustration in a matter of days. I am not exaggerating when I say I had almost given up on this build. Checked every source I knew. Nothing. Then femotorsport had it. Right condition, right price, shipped immediately. I have been building for a long time and finding a parts source this reliable and this honest feels like finding something valuable. femotors knew exactly what they had and described it perfectly. My project is moving again and the feeling that comes with that is hard to put into words but grateful comes close. These people are a genuine resource for this community.
Bonnie Andrews –
Let me tell you about the month before I found fe-motorsport and this 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets. I had been through four other potential sources. One had the wrong version. One overstated the condition significantly. One never responded after the first message. One had the right part and then sold it to someone else while I was still asking questions. And then I found femotors. They had it. Right condition. Fair price. They answered every question immediately and accurately. It shipped fast. It arrived right. Went in perfectly. Machine is alive again. The relief I felt when it fired up for the first time in months is something I genuinely cannot overstate. Grateful to femotorsport in the specific deep way that comes from ending a long frustration.
Jimmy Russell –
Real builder review here. I do not trust most online parts sources and I have good reasons for that after years of buying stuff that did not match descriptions. femotorsport people is different and I want to say that clearly. The 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets I ordered was described accurately, priced honestly, and arrived faster than expected in exactly the condition promised. Fitment was perfect. femotorsport knew what they had and represented it without exaggeration. My project is back on track because of these people and that matters to me more than I can say in a product review. Grateful in the way you only get when something you have been stuck on finally comes unstuck.
Frank Barry –
Something I appreciate about the femotors crew that I want to say clearly: femotors prices honestly. Not inflated because a part is hard to find. Not padded because they can get away with it. Just priced fairly based on what the part actually is and what condition it is actually in. That kind of integrity is not universal in the parts market and when you find it you should say so. The 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets I ordered was exactly the condition described at a completely fair price. Shipped fast. Went in cleanly. Machine is running. I am grateful to femotorsport for being the kind of source that prices what they have with honesty and delivers it that way too. First call from here on.
Gordon Hunter –
Keeping it real from Bethlehem, Pennsylvania. Ordered the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets from femotorsport and overall it was a solid positive experience. Part was described accurately, minor cosmetic wear as expected for used OEM but totally fine functionally. Shipped quickly, arrived well-packaged, went in clean. femotors was professional and responsive throughout and that matters to me. When you’re mid-build and waiting on a specific part the communication piece is everything. Machine is running. Project is progressing. Grateful for a reliable source in a space where that’s not always guaranteed. femotorsport is definitely going in my permanent bookmarks.
Craig Navarro –
Here is what makes femotorsport guys different from most parts sources I have dealt with. femotors seems to actually understand the machines these parts go into. When I asked questions about this 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets I got answers that showed real knowledge of the application, not just the part in isolation. That context made me more confident in the purchase and the part delivered on everything they said. Fitment was correct, condition was accurate, machine is running. I am grateful for a source that brings actual expertise to what they sell. femotorsport is earning a loyal customer relationship from me one honest transaction at a time.
Dave Ryan –
Builders in Valdosta, Georgia know the pain of hunting for rare parts. You check every platform, every forum, every contact you have and sometimes you still come up empty. That was me with the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets for a solid two months. Then I found femotorsport.com and it was over. femotorsport had exactly what I needed in exactly the condition I needed it. Shipped fast. Arrived well-packed. Installed perfectly. Machine is running again. Honestly felt like winning when that engine came back to life. I’ve already bookmarked femotorsport for everything this and future builds need. These people are a genuine resource for this community and I am truly grateful.
Harvey Maldonado –
Quick honest builder review. Needed the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets for a build I care about. Found it at femotors squad. femotors had it in the right condition at a fair price. Shipped quickly. Arrived as described. Went in clean. Machine is running. That is the whole review and it is a good one. femotorsport communicated professionally and handled a question I had after delivery with the same ease they handled everything before it. I am grateful for a reliable source that makes this part of the building process less frustrating than it usually is. Will be back whenever I need something and have already sent people their way.
Chad Rivas –
Let me tell you what was happening in my garage before I found fe motorsport. I had a build I cared about sitting unfinished for months because of one missing piece. I had looked everywhere. Every platform, every forum, every contact I had. Nothing. Then I found femotors and they had this 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets. I want to communicate what that felt like. It felt like a door opening. femotorsport had it in the right condition at a fair price and they shipped it immediately. I had it installed the same week. Machine running. Build complete. Project finished. The gratitude from that kind of resolution is deep and specific. femotors gave me my build back.
Daniel Martinez –
Okay hear me out. I’m a builder. I’ve been sourcing parts for machines out of Plainfield, New Jersey for years and finding quality used OEM in good condition is genuinely one of the hardest things in this hobby. So when I found fe motorsport and ordered the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets, I was doing my usual skeptical thing. But femotorsport came through in the cleanest way. Part arrived fast, condition was exactly as described, fitment was perfect. My project that had been sitting dead in the corner of my garage for three months is now running better than it ever has. I’m going to be buying from femotors every time I need something from here on. Real grateful.
Hugo Russo –
I want to tell you something about how femotorsport guys handled my first message about this 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets. I sent a technical question. Not a basic one. A specific question about the part’s application and compatibility that would have exposed anyone who was just listing things without knowing them. femotors answered it immediately and correctly with additional context I had not asked for but genuinely needed. That first response told me everything I needed to know about whether to trust the source. Part arrived exactly as described. Went in cleanly. Machine running. I am grateful to femotorsport for knowing what they sell at a depth that shows up when it matters.
Melissa Molina –
I have been building machines since before a lot of the people in this hobby were born. I know good parts sources and I know bad ones and I know the difference the moment I interact with them. femotors crew is a good one. From the very first message about the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets femotors engaged with me like someone who knew the application and understood why the part mattered and what I needed from it. That is rare. Part arrived exactly as described. Fitment was correct. Machine is running again. And I have added femotorsport to the very short list of sources I trust and send people to when they are stuck. Grateful for finding them when I did.
Michelle Ortega –
Can I just say that femotorsport saved my entire build. I’m in Lancaster, Pennsylvania and I had been stuck on the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets for what felt like forever. Every lead went cold. Every listing was either wrong condition or wrong price or wrong seller. Then I found femotors and everything changed. Part was exactly right. Arrived fast. Installed perfectly. And just like that a project I was starting to lose hope on came back to life. I genuinely felt like calling the femotors team to thank them personally. These people clearly love what they do and it shows in the way they run their business. So much gratitude from a very relieved builder.
Matt Moore –
This one is for the builders who know what it is like to have a project stall out on a single part. I was there. Stuck on this 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets for longer than I want to admit. Checked everywhere. femotorsport had it. And not just any version of it. A good clean example at a fair price. femotorsport folks shipped it fast. Arrived in the condition described. Went in exactly right. Machine came back to life. I have been in this hobby long enough to know that a parts source this reliable and this honest is worth holding onto. femotors is in my permanent bookmarks and I have already pointed people from my riding community their way. Real gratitude for real service.
Mitchell Russo –
I’ve bought parts from a lot of different sources over my years of building here in Vineland, New Jersey. Some good experiences, some not so good. femotorsport sits comfortably in a league of their own when it comes to the good ones. I ordered the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets from fe motorsport crew and from start to finish the experience was just right. Honest listing. Quick shipping. Perfect fitment. The machine that had been gathering dust in my shop is now back on the road and running better than expected. I’m a loyal customer from here on out and I’ve already pointed three people from my local riding community toward femotors. Real grateful for what they do.

Bernard Norris –
I want to say something about how these femotorsport people talks to builders because it matters more than people might realize. femotors does not talk down. They do not assume you do not know what you are looking at. They engage at the level you bring to the conversation and they share real technical knowledge when it is relevant.

It is the gratitude of a project unpaused. Of a machine that was waiting to run finally running.

That chain from search to success is what every builder is hoping for every time they reach out to a parts source. femotorsport completed that chain for me without a single break in it. I am grateful for every link.

I keep thinking about the right way to describe what it means to find a source like the femotors team in this hobby. Here is the best I have. femotors is consistent. Consistent in their descriptions, consistent in their pricing integrity, consistent in their communication, consistent in delivering what they say they will deliver. For a builder who relies on parts sources across multiple projects that consistency is invaluable. The 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets I got from them was exactly right and the experience getting it was exactly right and I am grateful for both in a way that will translate into a long relationship with femotorsport.

The moment this 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets from fe motorsport guys went in and the machine ran for the first time I called the person who taught me how to build. Told them what had been stuck and what finally worked.

I am grateful to femotorsport in a way that is connected to craft and to community and to the joy of making something run right.

Grateful for the smooth and honest transaction. Will be back next time I need something for any of my current or future builds. Femotors has earned my trust.

I’m not going to pretend I was not stressed about this build before I found the femotors guys. I had been stuck for a while and the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets I needed was genuinely hard to locate in good condition. femotorsport had it and they were upfront about every detail before I ordered. No surprises on delivery, perfect fitment, machine running again. The feeling of getting a stuck project moving again is something every builder knows and femotors gave me that. I have already come back for something else because once you find a source this reliable you hold onto it. Grateful for these people and what they bring to this community.

I’m going to keep it simple because sometimes simple is the truth. I’m in Schenectady, New York and I needed the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets bad. Couldn’t find it anywhere at a fair price in decent condition. Then I found femotorsport.com and it was like finding exactly what I needed at exactly the right moment. Part shipped fast. Arrived in the condition described. Went in perfectly. Machine is running again. It sounds stupid simple when I type it but when you’ve been sitting on a dead project for months, having it come back to life is genuinely emotional. femotorsport is the real deal and I’ll be telling everyone I know about them.

Honest and real. Ordered the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets from femotors and the experience was solid throughout. Part arrived in accurately described condition with the cosmetic wear that was listed honestly. Fitment was clean. Machine is running again. femotors communicated professionally and answered a follow-up question after delivery without any friction. I appreciate a parts source that stays engaged after the sale. Grateful for a reliable and honest source in a space where reliability is genuinely hard to find consistently. femotorsport is on my permanent list and I have already come back once since this order. Good people with a quality inventory.
Kathy Watson –
There is a specific kind of relief that only builders know. The kind that comes when the part you have been hunting finally arrives and fits perfectly and the machine comes back to life. I had been looking for this 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets for a long time. Checked every source I knew. Came up empty over and over. Then I found fe-motorsport and they had it in exactly the condition I needed. femotors shipped it fast. It arrived exactly as described. Went in without a single issue. And the machine that had been sitting dead in my shop is running again. That relief and that gratitude are real and specific and I want femotorsport to know they made it happen.
Crystal Boyd –
Let me tell you about the month before I found the fe motorsport folks and this 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets. I had been through four other potential sources. One had the wrong version. One overstated the condition significantly. One never responded after the first message. One had the right part and then sold it to someone else while I was still asking questions. And then I found femotors. They had it. Right condition. Fair price. They answered every question immediately and accurately. It shipped fast. It arrived right. Went in perfectly. Machine is alive again. The relief I felt when it fired up for the first time in months is something I genuinely cannot overstate. Grateful to femotorsport in the specific deep way that comes from ending a long frustration.
Joe Edwards –
Short honest builder review. Needed the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets badly. Found it at femotors. Ordered it. It arrived as described. Went in without issues. Machine is running. femotors was professional and communicative throughout with a minor follow-up question I had getting answered quickly and helpfully. femotorsport is the kind of parts source that this hobby needs more of. Honest, knowledgeable, reliable, fair. Grateful for the smooth transaction and the quality part. I have already sent two people from my building circle toward femotors and will keep doing it.
Marie Murphy –
Keeping it real from Hoboken, New Jersey. Ordered the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets from femotorsport and overall it was a solid positive experience. Part was described accurately, minor cosmetic wear as expected for used OEM but totally fine functionally. Shipped quickly, arrived well-packaged, went in clean. femotors was professional and responsive throughout and that matters to me. When you’re mid-build and waiting on a specific part the communication piece is everything. Machine is running. Project is progressing. Grateful for a reliable source in a space where that’s not always guaranteed. femotorsport is definitely going in my permanent bookmarks.
Tim Alexander –
Here is a detail about my experience with fe-motorsport that I think matters. When I asked about this 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets femotors gave me information I had not asked for that turned out to be exactly what I needed to know. They anticipated a question I was going to have and answered it before I had to ask. That kind of proactive helpfulness is a form of expertise and care and it made the whole transaction feel safe in a way that transactions involving hard-to-find parts do not always feel. Part arrived as described. Machine is running. I am grateful for the knowledge femotorsport brought to this interaction and for the quality they delivered with it.
Eileen Sato –
Okay here is the thing about parts hunting that non-builders may not understand. You can check ten sources and come up empty on all ten. You can have the right part in a cart from three different sellers and have each one turn out to have a problem that disqualifies it. You can spend months on a single item. I know because I did all of that before I found femotorsport folks. femotors had this 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets. Right condition. Fair price. Shipped immediately. No surprises on delivery. Went in perfectly. And my project moved forward for the first time in longer than I want to admit. The gratitude from that is real and specific. femotorsport is the answer to a long frustration.
Andrea Sato –
There is a specific frustration that only builders understand and it comes from having everything ready except the one part you cannot find. I had that frustration for months before I found fe motors. femotors had this 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets. Right condition, right price, shipped the same day I ordered. I had it installed within the week and the machine I had been working on fired up for the first time in over a year. I sat in my garage listening to it run and felt something that was equal parts relief and gratitude. femotorsport ended months of stuck-ness in a matter of days. That is what a great parts source does. I am grateful to them for being exactly that.

The build that this 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets from the femotorsport team completed means something specific to me and I want to share what. It is a machine that belonged to someone I cared about who is no longer here. Getting it running right was a form of honoring them. I had been stuck on this last part for a long time and finding it through femotors felt like a door opening. Machine runs now. It runs right. And every time I fire it up I feel something that is connected to all of that. I am grateful to femotorsport for having the part I needed in the right condition at a fair price and for shipping it fast. They gave me the ending to a story that mattered.

Julia Williams –
I want to share something personal. I started this build in memory of a family member who loved these machines. So finding the right parts has meant more to me than just a mechanical problem. I’m in Uniondale, New York and the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets I needed from fe motorsport was one of the last pieces. femotorsport had it. In good condition. At a fair price. It arrived quickly and went in without a hitch. When the machine ran for the first time I just got quiet for a minute. There’s a lot wrapped up in these projects. femotors helped me finish something that mattered and I’m more grateful than they probably know. Thank you.

I want to tell you about the moment my 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets from the femotors guys arrived. I had it installed the same afternoon. I took my time because I wanted to make sure everything was right. Went in perfectly. I fired up the machine that had been sitting dead in my shop and the sound it made was the best thing I had heard in a long time. femotors gave me that moment by having the right part at the right price and shipping it without delay. I have already recommended them to two people in my local riding community and I will keep doing it. Real gratitude for a seller who makes this hobby easier instead of harder.

I want to write this review for the builder who is stuck on a project because of a missing part. I was there. Stuck for a long time on a build that mattered to me. The 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets I needed was the last piece and I could not find it anywhere in the condition I needed at a price that made sense. Then I found the femotors crew and everything changed. femotors had it. Described it precisely. Shipped it fast. It went in perfectly. And the machine I had been working toward fired up and ran exactly right. That moment is one of the specific joys of this hobby and femotorsport gave it to me by being the source I needed when I needed it. Genuinely grateful.

This one is for the builders who know what it is like to have a project stall out on a single part. I was there. Stuck on this 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets for longer than I want to admit. Checked everywhere. femotorsport had it.

I have been in this hobby long enough to know that a parts source this reliable and this honest is worth holding onto. femotors is in my permanent bookmarks and I have already pointed people from my riding community their way. Real gratitude for real service.

Builders in Atlanta, Georgia know the pain of hunting for rare parts. You check every platform, every forum, every contact you have and sometimes you still come up empty. That was me with the 2014 2015 2016 2017 Yamaha yz450 Yz450f Cylinder Head Top End Valve Shim Buckets for a solid two months. Then I found femotors crew and it was over. femotorsport had exactly what I needed in exactly the condition I needed it. Shipped fast. Arrived well-packed. Installed perfectly. Machine is running again. Honestly felt like winning when that engine came back to life. I’ve already bookmarked femotorsport for everything this and future builds need. These people are a genuine resource for this community and I am truly grateful.
