Depends who puts em together. Anyone can throw it together, but you really have to be precise and do everything good to have the most power. Also could be if it was jetted wrong. Also the rider.

ya rider error is a big thing

a 440 doesn't rev like a 406 or 416, 440's have torque, but also it who and how it put together, porting, carb, cam, compression, tires, gearing all play a huge part. Its also rider skill and shifting speed
