But this is my assumption, a motor with a long stroke would need balance shafts otherwise it would just sake itself to death. maybe not now...maybe not immediatly, but perhaps in the future. there is a reason why its there and relativily hard to get to.
have people noticed any long term effects with thier balance shafts removed?
I don't there are very many people that have removed the shafts and have high mileage yet. But there will be an affect some how. It can cause uneven bore where too.
