180cc Stroker Crank

Genuine Honda crankshaft welded and ground, producing .160" more stroke

Requires UT2 GX160 piston with standard length (3.303) rod

Crank requires balancing!!!!!!

.060 Stroker Crank

Genuine Honda crankshaft welded and ground, producing .060 more stroke

Puts piston at -.010 to TDC on Honda blocks (Chinese OHVs will vary)

Crank requires balancing (58 grams total, 29 per counterweight for ARC rod and flat-top piston)

Allows 202cc (standard) to 207cc (.030) with OEM pistons

+.175 Billet Stroker Crankshaft - GX200 & 6.5 OHV

This crankshaft is machined from a solid bar of 4140 steel and will give you .175" more stroke than the stock Honda/Clone 196cc crankshaft (.136" longer in a Predator 212) with far superior strength. It uses a 1" journal and requires a connecting rod (#6265 drop-in or #6765) and a Wiseco piston

Crank and required connecting rods are clearanced for most cam applications, but some additional machining may be required with high lift/high duration cams.

Crank is designed to be used with Honda GX200/Clone 196cc flywheel taper.

You must use flywheel key number included with the crank or our offset key. Standard GX or Clone keys will not work.

If using the #6765 rod, the top of the piston will need to be machined approximately .100". Use only 2-ring pistons! (Warning: Do not machine the top of the 3-ring pistons.)

If using the #6265 rod, either a 3-ring or 2-ring piston can be used.

Outer 3rd/4th bearing supports are highly recommended

Pistons larger than 2.815" will require balancing

*Note: No warranties or returns on billet crankshafts
