I am curious to know your opinion about the flywheel: such lightweight unit is, in my opinion, giving extra work to the compensator, which would have already an hard-time dealing with a big V-twin. I could see this as a reason for the compensator giving up his job so early. Honestly I cannot find a technical reason for this decision, because the S&S is not really a fast engine which needs revving up and down like crazy, it is not built for this. I am dealing with industrial machinery all the time, maybe I miss some information about cars and motorbikes. Can anybody help me ?
