My fairly new RT-s SM [250 miles, bought used] has developed a noise seeming to come from underneath the left side pegs [inside cover]. It sounds like a squeeking with a scraping edge to it. IT semms to be speed based , not RPM based and is worse under stain [going uphill] and not so bad on straight aways and absent downhill. It is present in all gears but I don't notice it in reverse. As I said it seems more speed based the RPM based but I can't tell for sure. I guess a trip to the dealer is in order but I'm scared of what they'll find. Sounds like a clutrh or transmission. Does anyone have any ideas ???? John form NY
