Don't buy these crankshafts, it will throw the big end bearing before you get 5hours on it. This is the worst quality product I have ever seen, it is nearly broke in and it detonated the big end bearing, which sent copper all over my engine, taking out all the bearings, crank, piston and jug, an of course the cheap crank from hot dogs is roast too.
Save your money people, these bikes are very expensive, buy the OEM, or put some SKF bearings it it. It's not if it will fail in a few hours, from what I have read online, this will definitely fail in less than 10 hours!
