Yes ,I agree the motor was not the best choice,but we need to remember that on bike motors there is an internal primary reduction that is between the crankshaft and the tranny input shaft that reduces the engine RPM input to the tranny to more reasonable levels.Example -busa at 12,500 engine rpm redline X 1.596 primary reduction brings tranny input shaft to 7832 rpm. Same as many high putput V8's and 4 bangers alike. While I agree he would probably be better served with a torque monster instead of the bike engine I cannot blame the high rpm as the culprit. True ;most rice burners are not torque monsters and ,if it were me,I'd have chosen a different engine.
