Based on what ive seen on dads bike,i wouldn,t fit yosh cams without fitting a thinner head gasket and or reducing the combustion chamber size by shaving the head.Get the compression up to 12 or more and don,t dial them in too late and it will be good from 3000 up instead of from 6000 up.dads is up to 186hp/107ft/lbs.rapid busa made 188hp/108ft/lbs on the same dyno.dads has compression,,ported head and yosh cams.
