i bought an mc18 r4j, which has been parked up for years. the bike is now running and starting fine. i have a query because there seems to be the normal amount of smoke coming out of rh exhaust pipe and a little amount smoke from lh pipe (lower cylinder). i would have thought that there should be the same amount of smoke from each exhaust. i checked and both cylinders are firing, so my concern is that, there is no 2 stroke oil getting to the bottom cylinder. is there anyway of testing this??? should the upper cylinder produce more smoke than the lower cylinder?? can someone let me know, because i am afraid to leave the bike running and i dont want to seize it. the bike had a full rebuild before it was parked up.
