This might be a question for John Chaterlea.?
Yesterday I decided to change the gearbox oil from 30 grade engine oil (as BSA recommended) to Gear Oil 80-90 (both similar in viscosity), and add some slippy stuff to quieten the 3rd gear growl and hopefully to improve shift. Nothing wrong with the 30 grade - fairly new.
However, the starter motor is in the way for access to the drain plug (You'd have thought I would have thought of this before
). I could get it out with much spanner work, but no finger access to get the thread started to reinstall the plug. I decided to leave it alone but add some slippy (Penrite Shift-eze 10%).
Next option is to remove the outer cover and tilt the bike over, or remove the gear indent plunger??
Any easy solutions?
