Mossbargger Engine Installed 5-10-02 Yamahonda engine removed, the head bolts keep coming loose I will have to take the engine apart and see what is happening, maybe the studs are stretching or backing out? While I had the engine out I decided to replace the rubber engine mounts, one was in pretty bad shape and all 3 the rubber was pretty dry rotted/ Here it is installed. Anybody identify that pipe? So far it runs good, need to make some jetting changes because it is a little fat in the mid range and on the top end, the engine does not seem to have as much power as the Yamaha engine did but I suspect the pipe is a lot of the problem I need to find a pipe that I know works well with this cylinder, some clutch changes might also need to be made I think removing one washer from the Power Bloc will make a difference, right now I will concentrate on getting the engine broke in then after a few hours of run time will do some testing and tuning. More later...
