had that thunk or clunking noise in the area of kebc housing . told my dealer about it he says bring it in we'll fix it no problem have no idea what all they did but I do know they put a new type of belt on .pick it up from the dealer notice what looked like grease under the housing under the round section got home it was worse than before started to feel where the noise was coming from something had came apart from the inside tore a hole about the size of a silver dollar in the Kebc housing and yes not knowing there was a hole stuck my finger in the hole scared the crap out of me. They had to rob parts from another new 650 to fix mine. Dealer told me he had no idea what caused that hole he didn't know his service writer had already told me a bushing came loose. dealer is a liar So be careful

 

Is there a new type belt out for the 650 or is a bull story too.
