Here's what's included with this kit:
You mail in your cylinder to us, and we'll remanufacture it and send it back to you in the kit. PLEASE NOTE: you will be required to mail in your old cylinder prior to us shipping out the kit. All cylinders must be no larger than 2nd oversize(.020/.50mm). If you don't have a good cylinder to mail in, we do try to keep cylinders available for purchase for an additional $75 (if needing one of our cores please contact us at that time for core availability).
All cylinders are ultrasonically cleaned, bead blasted and precision bored and honed.
We'll include a matched oversized piston and ring kit including piston pin and circlips.
We'll include a top end gasket kit.
We'll include instructions for proper break-in procedures for your new top end rebuild.
This kit will come ready to bolt on for a quick and easy top end rebuild.
Let's face it. All machine work is not equal. When it comes to machining, you get what you pay for. We invest the time in every cylinder that we sell to provide only the highest quality workmanship to very strict tolerances making our machine work second to none. We have shops all around the world that rely on us every day to provide them with the quality machining they've come to expect over the years. The machining you receive will be to the same quality standards. The cylinder is precisely matched with an oversized piston kit that includes the correct oversized piston, piston rings, piston pin and circlips. No more worries about having machine work performed or wasting time back and forth trying to have your old cylinder machined. Simply mail us your old cylinder with payment, and we can get you up and running again. We also offer repair manuals for $26.95 as well. These will walk you through every step of the disassembly and rebuild and also include tolerances, torque specs etc, so be sure to check out our selection.
