So i started the bike for the first time in 3 or 4 months the other day (i keep it in the house) i noticed straight away that the left pipe (gear kick side) was smoking twice as much as the right pipe. i left it warm up and took her for a spin for 20 mins. when i got back there was minimal difference in the pipes but the left was still smoking a small bit more. I seen a thread up like this a while ago for a MC21. people were saying it could be gearbox fluid but obviously with this being a 28 we dont have that problem. im thinking a crank seal could be on the way out? any help appreciated
