My 2015 three wheeler left the dealer only a few days ago. I will of course direct any problems to them. But I am technically interested in burning rubber pongs at take off or on any kind of hill start. Also thought the belt jumped a couple of cogs .
The belt doesn't feel loose ( OK, 1" play roughly and 45 deg twist etc) and being toothed I can't see it slipping like a worn V belt.
Anyone thoughts from the experts?
