SPECIAL PROMO: Hand lapped Piston & Sleeve break in service is included in all Clockwork modified engines.
what dose that mean?
it means that the piston and sleeve are hand fitted for the best possible fit. It makes the break in much easier and shorter. It's also alot less stressful on your engine internalls. When i got mine, it was about as closest as a fit you can get and break in was way better then what i was used too.
