This kit is the same as the Stroker Kit 4 but also includes the Mikuni VM26mm carburetor for much better performance. Its an affordable kit that will convert your TB 88cc Race Head kit into a powerful open class 117cc engine with tons of torque!

Key Features:
     •51mm Crankshaft with NTN bearings
     •Lightweight 54mm aluminum cylinder with steel sleeve, cast in mounts for skid plates, and large cooling fins.
     •High compression piston with rings, pin, & clips
     •Crankcase and clutch cover gaskets
     •Head gasket kit
     •Genuine Mikuni VM26mm Performance Carb
     •Intake Kit
     •Jet kit with 3 different sizes (Stock size is a #195 - Extra jets sizes of 155, 165 & 175)
     •Throttle Cable
     •Dual Layered Foam Air Filter

As with all 117cc kits on the market, installation requires engine to be disassembled and case bored. Therefore, we highly recommend a professional technician install this kit and the cases bored by a reputable machine shop. If you plan on installing the kit 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 and both manuals cover this.

Recommeded Products:
     •High volume oil pump
     •Oil Cooler (available in this section)
     •CR8HSA spark plug (not required, but recommended)

Note: If you are running the stock Honda clutch, we also recommend upgrading yours to the Manual Clutch Kit with the Billet clutch housing. If you have one of our regular Manual Clutch kits with the cast housing, we highly recommend upgrading the housing to our Billet Housing. The stock housing in both the Honda clutch and our regular Manual Clutch kit is not made for this type of power and may fail due to the extra fatigue.
Also, do not tighten the clutch nut with a hammer and screw driver - it must be torqued on!
