R50/5 Final drive pinion bearing removal

Any one done this?
I have borrowed the necessary tools to undo nut and remove threaded seal ring.
I will obviously have to heat the final drive housing but just wondering the best way to remove shaft with bearing. There's not a lot to get hold of or get at with a drift.

Fork Oil

Sorry to bring this perianal up again but what's the current thinking on fork oil?
I always got by with automatic transmission oil.
Bike in question is R50/5.

Thanks guys. More involved than first thought.

/5 Front Drum Brake

The eccentric cam in the front drum brake.
Am at a loss as to what it does and its function.

R50/5 Tyres

Any comments, opinions, experience on fitting Mitas H-06 tyres (£120 a pair) to a R50/5 that will be ridden at sensible speeds?
I have them on my Matchless and give me no issues.
