I have 2003 GSXR 1000 stock motor that I am running in 2005 gsxr 600 frame, extended-68 wheel base, lowered to about 2in off ground. So I kept the 180 rim/tire and am using a shinko hook up. This is hand clutch, foot shift bike. I am trying to get and idea of a gear ratio.I am currently running 16/45, but am thinking that might be a little deep. 1/4 trap speed is 138, 1/8 speed is about 115. I am going through the 1/4 in about 1/3 into 5th gear. I have 16/17 front sprockets, and a 45/43 rear sprockets. I see lots of gearing ideas for heavy riders, but none for us lighter guys. I am currently running 16/45, but am thinking might be a little deep. 1/4 trap speed is 138, 1/8 speed is about 115. Stock gearing I believe is 17/41. I weigh 155 in gear. Any ideas on what to run with my current spocket set up? I am trying to get some ideas from people running 1.35-1.45 60ft with stock motors and light weight riders.
