This kit requires that your Stock Cylinder be Resleeved, Finish Bored and Honed. We offer that service for $195, or your local machine shop can do the work for you. This kit also requires that your engine cases be machined in order to make room for the new sleeve. If you’re interested in having us do the machine work, please contact us. You’ll need to send us your cylinder and bare engine cases.

NOTES:

The compression ratio of this piston is 13:1. We recommend that you run 110 octane minimum for optimal engine life. Higher octane fuel burns cleaner and improves engine life — and ultimately it’s a lot cheaper than having to rebuild your top end!!
