Hy leutz, am about to buy me a RS 125. The problem is that many leads advise me against it because, 125ers supposedly often have problems with cylinders and pistons.So often a milling cutter. Question is: 1. Is that true? 2. How much would the fun cost me if I had a muzzler? 3. Can this be caused because of the throttle from 34 to 15hp? Would it be cool if you were to help: thx
