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.

Recommend purchasing the Upgrade Disk Kit available at TboltUSA . 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. We offer a Clutch tool at TboltUSA See the TECH DATA Info section for additional information on our performance products and links to instructions for the top end and oil pump.
