just wondering if a stock 05 zx-6r sprocket will work on my 10r. i got one of ebay for under 10 bucks; its a 43 tooth. am i gonna need a different chain? i know the 636 uses a 520 chain, didnt know if that makes a diff. i would love to be able to just throw this one on for now, moneys kinds tight right now so i cant get the 520 chain conversion. thanks guys.
