Hi from Germany. I got. my used T-Boss 550. Wehen i take off the throttle there is a noise, loud click from the back. It Domes from differential gear back. There is a gap in the powertrain back. My dealer says this ist normal and no defect. Please Watch the little Video, Which Shows the gap and the noise. Do have other T-Boss same Thing? Thanks Video.mov

Moin from Germany. Anybody knows the Size of the Belt for the T-Boss 550? So i can choose one from the aftermarket? The original is very expensive here? For example Mitsuboshi or else……Thanks
