***NEW** TB Stroker Kit 6

8/28/06 The kit now includes the proven Mikuni VM26 carburetor which will provide better performance and ease of tuning.  6/26/06 Our Race Head has been updated for even more performance!  It now has 25/22mm valves with better porting/flow.  We also kept the combustion chamber the same size and changed the angle of the valves slightly.

This kit is the complete kit to convert your stock motor 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. Key features include the following parts:

- 51mm Crankshaft with NTN bearings
- NEW Race Head – Larger valves (now 25/22mm) and better flow for increased performance. Also has bigger cooling fins. Includes all necessary parts and comes assembled!
- High performance race camshaft
- 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
- NEW Genuine Mikuni VM26mm Performance Carb
- Intake Kit for the Race head
- Jet kit with 3 different sizes (Stock size is a #195 - Extra jets sizes of 155, 165 & 175)
- Throttle Cable
- NEW Dual Layered Foam 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 (available in this section)
- 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 a regular TB Manual Clutch kit with the cast housing, we highly recommend upgrading the housing to a TB 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. Additionally, if you purchased a TB Manual Clutch Kit prior to 6/30/05, we recommend purchasing the Upgrade Disk Kit that we have available.  Also, do not tighten the clutch nut with a hammer and screw driver - it must be torqued on!
