Great respect for all Pat's work, but 80 mph + on the salt at Bonneville and a "flats" record holder, well 'kinda think that speaks volumes about his advice on the small engines & moto bikes in general!
Looking at Jeff's engine work, design and bike construction one can't possibly miss seeing his skill and dedication to getting it right and he has; on multiple builds, including the sprint, that's the center piece of this thread, and he's quite deserving of all the praise he's received & will continue to receive....
