Complete performance replacement crankshaft

• Mix gas/oil 32:1 – then make jetting right. The bottom rod bearing and engine in general needs more oil.
• Always check crank seals – replace with every rebuild and pressure check bottom end to ensure crank seals are in good working condition.
o Look for burrs in crankcases where seals go in. The seal should press in smoothly. Some newer case finishes are rough where the crank seal openings are machined.
• Perform leakdown test on engine. Look specifically for intake leaks in reed / carb boot and crank seals. Some OEM reed cages aren’t properly sealing between the reed block and the cylinder side.
• MX crank life is 40 hrs..
o Mod motors and heavier or really fast riders - 30 hrs. max.
• Always clean everything before assembly.
• Set side clearance to .026” (Wossner cranks are set at .024 - .028”)
