So my bike sits for a few weeks, a thick golden puddle underneath the engine, coming from the shift rod seal going into the sidecover....Question is, can I replace the seal without removing the side cover? Pinion boss cracked and sealed with JB Weld...Don't really want to see all that! Afraid of what I might find! Dead cylinder fixxed by removing and meticulously cleaning carbs...Amazing how this bike breaks just by sitting a few weeks....
