I purchased my 2006 in 2010. It had less than 6,000 miles on it when I bought it and now has about 26,000. I use it almost solely for commuting on country roads and the freeway. I have almost always had the work done by a mechanic that is supposed to know what he is doing. That guy sold the shop and the new guy asked me about the noise coming from the back end. When the motor is off and I push the scoot there is some sort of mechanical grumbling. I thought it was just normal noise from a CVT. Is it? This new mechanic said he can open the back end to check. As long as he is in there he should replace the belt – never done under my ownership – and make any other corrections necessary. The estimated cost is just short of $400. OUCH! Could this be a belt issue, a slider issue, a clutch issue...?
