Replace the main weak link in your Hayabusa motor with this complete roller cam chain conversion kit. This kit is for serious racers that cannot have cam timing fluctuations and/or the risk of the OEM style hy-vo cam chain breaking.
The kit contains special upper and lower cam drive sprockets, camshaft adaptors, and cam chain. Another benefit of this setup is that longer cam chains are available for racers using the longer stroker crankshafts with tall stroker plates.

I highly recommend the roller chain conversion kit. The OEM hy-vo chain has always been a problem waiting to happen. Sometimes the wait is not that long. The roller chain is much better set up I can give examples of why the stock chain fails but this review would be rather long..
