Shortys,Thats exactly what it sounds like. Growling. Ohhhhhh shit, I guess I better plan on taking this thing apart before it is too late. Will my local machine shop be able to do this or should I seek somebody who has experience with welding these cranks? Anything else I should do while I have her split open? I guess a top end is a must as well? damnit.....Oh well better that I find out now and do it before it is too late.
