Hi guy's for my first post I thought I'd ask a question , I have an MC18 (88 model) and at low revs it pops out of the left hand pipe, bottom cylinder and when the wires are disconnected it doesn't make a difference , it doesn't seem to be firing , when I take the plug out hte plug has weak spark and fires intermitantly.I've tried swapping plugs , coils , and checked the earth wires but it still does it , I can't find anything else that would cause it . Any idea's because I'm stumped .Oh forgot to add it's fine at high revs above 3000 rpm
Thanks in advance for your replies .
