Great product and as for the other guy saying the plastic melted, we'll he needs to check jetting because if his bike got that hot to melt the plastic he had other issues.

Crank lasted approx 10 hrs. Plastic parts are used on crank assembly. The plastic melted, broke off and entered low end bearing.

I seized up my crank bearing after riding WOT for too long. Looking back that wasn't so smart but after getting over the fact that I cost myself money and time lost from riding I ordered this kit. It arrived about a week after placing my order with everything needed to complete a bottom end rebuild. Really good packaging too. Wiseco takes pride in their products. In comparison to the stock crank this one appears to be higher quality. I like the price and everything fit perfect. Riding this bike now is a night and day difference. It feels like the RPM's are achieved faster and smoother. This bike really rips with little effort. The only thing I wish this kit included was the four bearings that support the transmission. Other than that price, quality and performance are worth it.
