Trail Bike 108 Stroker kit 2 This is an affordable kit that will convert your TB 88cc Race Head kit into a powerful open class 108cc engine

. 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.

The kit includes the following parts: - 51mm Crankshaft with NTN bearings

- Crankcase and clutch cover gaskets

- Head gasket kit

- 26mm mikuni carb kit

This kit requires engine disassemble and therefore, we highly recommend a professional technician install this kit. If you plan on doing it yourself, you will need to have a Clymer or Honda shop manual. Instructions do not come with the kits but the installation of the crankshaft is just like installing a stock Honda crankshaft. You should also have the following parts:

- High volume oil pump

- Oil Cooler

- Billet clutch hub


- If you purchased one of our Manual Clutch Kits prior to 6/30/05, will recommend purchasing the Upgrade Disk Kit that is available in this section of the Catalog. Additionally, we do not recommend the use of an inner rotor kit with this clutch (on a 108cc or larger engine) as it can lead to premature clutch failure due to extra fatigue placed on the clutch housing. Also, do not tighten the clutch nut with a hammer and screw driver - it must be torqued on! See the Performance Info section for additional information on our performance products and links to instructions for the top end and oil pump.
