Il let you guys know what i end up with , i went and dyno tuned it and it failed because my cluitch was slipping really bad ( stock clutch with HD springs) bike would hit 60 hp just slip and rev to the moon. I have a lock up from F.a.s.t on its way should be on by friday. Hopefully i can hit at least 85hp no problem
