I own a 2000 RC51 with and power commander and slip-ons. I need a new chain and I am going to buy a 520 conversion kit. The stock sprockets are 16/40. I am thinking of going with a 16/42, but a few sites have suggested a 15/41. I want quicker acceleration, but I don't want to do wheel stands every time I crack the throttle open. Is the 15/41 more for the track? Any suggestions?
