Hey guys, ive been doing a lot of reading about crank balancing these HT engine. It seems as thought most people use between a 53%-55% balancing factor which is fine. I'm trying to get up to about 8500-9000 rpms without vibrating things apart. I have an extra crank that I don't need to practice on from a 66cc engine, and im sure that any sort of balancing would do these engines justice.
I know that the 48cc crank was used and because of the heavier top end the engine vibrates like a mofo at higher rpms. In general for the 66cc do I begin with adding weight or removing weight to the crank?
As for the Crank balancing factor, is it that I add 53%-55% to the lower end of the crank (flywheel)?
I will be working on a crank balancing device that I can use to measure the weight of the crank.
