This is a 2006 8 ml stroker motor, built by White Knuckle Racing in Portland Oregon. All shafts and gears are keyed so no slippage, puts out around 85hp. It has a Makuni carb, same as Harley Davidson. The Clutch has been modified for the added HP. This is a fresh engine; it has not been installed in a rhino since I got it back. If you want to keep up with the razor 900 this is the engine for you. Included is a Muzzy duel exhaust worth 700 bucks and a spare heavy-duty drive belt. Asking $5000, that’s just the cost of the build, great deal, wont last. I have pics if you need them.
