Actually what I would really like is a motor with HUGE torque from idle to 3000, as I don't think my bike has been over 3000 rpm more than twice, I like to put along in a higher gear. An engine with big torque would be nice for passing, hill's, or just rolling up to 60-70 mph from 40 in high gear...
Thats why I think a big incher with maybe a different grind cam would be my ideal engine...
