Re: dynamic crankshaft balancing
it eats a piston, (i use the stock chinese piston) about every 100mi. im about to start performing some tricks on a new piston now. 41t sprocket and the pipe will not let it rev over 9800rpm which is about 39mph. 30-40 takes less than a second. any faster and ill start getting tickets and or die.
hmm.... mine comes with bearings and mine has been tested. ask them what balance factor they use. remember what i said about single cylinder cranks.
its not how fast you go... its how you go fast
actually, its how fast you get there
