Not problems of that nature, but my bike is in having the starter gears fitted, they’ve been done now but it appears the starter isn’t strong enough to turn the engine, it apparently starts on the kick start but whether I have the strength to kick it over yet is debatable and the reason I sent it in the first place to have the gears fitted, so it looks like I may have to source a new starter motor.
It used to whizz over when no gears were fitted but then again it wasn’t under load, I’m guessing it wants an overhaul of new brushes and cleaning but that could be a later project for me at some date.
