i bought an 07 r6 yesterday at an auction. after getting it home i noticed the speedometer was quite a bit off(70 is 60mph). then i did some looking and found that it was a vortex rear sprocket(47 teeth) and the chain says srx 530(or something close). im not sure about what the front sprocket it... how much will this throw my speedometer off and how much would it be to get the speedo calibrated?

Google search for a Speedohealer. Even with stock sprockets, the speedo will still not be 100% accurate. Your speedo will be off by roughly 8-10%.
