Hope some one will point me in the right area. I have a Paralever BMW R80GS with a Seibenrock 1000cc conversion kit. Is there a Suppertrapp exhaust that will fit this machine? I realise I could use a slip one plus an adapter but is there a special kit plus silencer available off the shelf? Will I have to re jet? I had a supertrapp on a DR 600 and was very pleased.
