TB Stroker Kit 4

This is an affordable kit that will convert your TB 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

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 (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 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! 

 Application:

- Honda Z50 1988-1999

- Honda XR50 All Years

- Honda CRF50 All Years
