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.  Simply mail us your old cylinder with payment, and we can get you up and running again. We also offer repair manuals 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.
