Convert your 88cc motor into a 108cc stroked animal with the 51mm Stroker Kit from Trail Bikes. This is an affordable kit that will convert your TB 88cc Race Head kit into a powerful open class 108cc engine (much more powerful than the common Chinese 107 and 125cc engines). Also - this crank was made specifically for the newer engines and thus - you will not have any fitment issues like trimming the piston skirts in order to clear the crank or the piston not lining up with the cylinder deck.
