Frequently Asked Questions

Q: Is this a big bore kit or a standard replacement?
A: This is a standard bore replacement cylinder (97mm). It does not require any additional machine work or modifications to your engine cases.

Q: Does it come with gaskets?
A: This listing is for the cylinder body only. We highly recommend purchasing a new top-end gasket kit and a piston kit to ensure a perfect seal during your rebuild.

Expert Pro-Tip: When working on the YZ450F, always check your cam chain tensioner during a top-end rebuild. If it has high mileage, it is a great time to replace it along with the new cylinder to prevent timing issues. Remember to lightly coat the cylinder walls with clean engine oil before sliding the piston in to prevent dry-start scuffing.
