Turn your 107″ M8 engine into a 117″ by simply boring your stock cylinders! No case modifications necessary, the factory 107″ can be safely bored from 3.937″ to 4.125″. These forged pistons are manufactured for us by CP-Carrillo in 3 different compression ratios (flat top compression ratio is 11.2:1 with an unmodified 87.5cc head) and feature 1.5mm compression rings with 3mm oil rings for superior oil control. Piston kits include pistons, rings, wrist pins and circlips. USA made!
