Both systems perform equally well when professionally done, so it really comes down to economics. You can expect a sleeved cylinder to give more life for the money. Re-plated cylinders are as close to original as you can get. So if your happy with your OEM plated cylinder you should have it re-plated. If not have it sleeved by a company that has the reputation, experience, and warrantees to protect your investment.


If you do it let us know how it turns out.

Well, I called Kustom-Kraft. The technician said they only keep records by the owner's name. No VIN search available.



He also recommended checking the piston size for a possible big bore kit but said that most KDX jobs are a simple replating.
