TB Parts Stroker Kit 1

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. Key features include the following parts:

- 51mm Crankshaft with NTN bearings
- Crankcase and clutch cover gaskets
- Head gasket kit

This kit requires engine disassembly 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
- CR8HSA spark plug (not required, but recommended)
- If you purchased a TB Manual Clutch Kit prior to 6/30/05, will recommend purchasing the Upgrade Disk Kit that we have available. 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. However, we offer an upgrade which allows use of inner rotor kits and larger displacement engines - Please see the Billet Housing upgrade we have available. Also, do not tighten the clutch nut with a hammer and screw driver - it must be torqued on!
