special06shee Posted October 23, 2014 Report Share Posted October 23, 2014 Depending on weight of rider/bike, motor/chassis setup, your Probably pretty close where ya at. For 300' anyway. 1 Quote Link to comment Share on other sites More sharing options...
4jokelol Posted October 23, 2014 Author Report Share Posted October 23, 2014 Had a guy tell me to run 15-40 he had same setup as me but on alcohol. And he weighs like 60 pounds less than me what u think? Quote Link to comment Share on other sites More sharing options...
Pasi S. Posted October 23, 2014 Report Share Posted October 23, 2014 Like special06shee already said, you need to give more info. I would think 60 puond lighter rider, burning methanol can pull longer gears or more tire. I have less power than you have and I was told to start from 3.0 ratio (15-45, 14-42) and go from there.
