i have a older GSXR 1100 motor and im wondering if a 13:57 gearing would work for 2nd gear?.....also i was wondering if anyone had Roland Kopes number so i could contact him with some questions
you know im not 100% when we go to our half male is just a front gear change..ex barona 13-51 and perris 14-51 but we all run in third gear, going up in the frint will lower you 900-1000 rpm
