Thanks so far, any ideas with the swing arm? Got the centre spindle out but the tube and 2 outer bushes are seized solid plus there seems to be some sort of o ring/rubber in there judging by the smell!!!!
Also flywheel nut LH or RH thread, managed to get the counter weight off though.
What were montesa thinking of with the gearbox sprocket.......... taper, keyway, left hand locking nut with lock washer maybe they thought the massive power and high speeds would cause problems
