117cc stroker kit 5 for honda 50's and 70's

117cc Stroker Kit 5

This kit is the same as the Stroker Kit 4 but also includes a 26mm carburetor for much better performance. Its an affordable kit that will convert your 88cc Race Head kit into a powerful open class 117cc engine (much more powerful than the common Chinese 107 and 125cc engines) with tons of torque! 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
- Lightweight 54mm aluminum cylinder with steel sleeve, cast in mounts for skid plates, and larger cooling fins.
- High compression piston with rings, pin, & clips
- Crankcase and clutch cover gaskets
- Head gasket kit
- 26mm Performance Carb
- Intake Kit
- Jet kit with 10 different sizes (kit not pictured - recommend starting with a #100 or #105 with the 117 kit)
- Throttle Cable
- Air Filter

As with all 117cc kits on the market, installation requires engine disassembly and case boring. 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. You should also have the following parts:

- High volume oil pump
- Oil Cooler (we do not carry these at the moment)
- CR8HSA spark plug (not required, but recommended)

Note: If you have one of our Manual Clutch kits, there has been no long term testing to see how it will hold up to the additional power with this new 117 kit. 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!
