Re: Hi From Southern Indiana first build
I think balancing would make a difference. It is my understanding that the outer rings on the cranks can be machined true and that helps a lot without actually getting into balancing them proper. I haven't tried any balancing but a friend of mine is an engine builder and will be receiving an engine from me soon and I will have more information when he tears it down. Done some porting and trimming the piston skirt and it seems to help.
