Is it possible to remove the Mk3 starter motor without stripping the primary down? I'm guessing not but hoping I might get lucky!

According to the service manual - yes.

Just the actual motor?

If so, yes.

Thanks chaps. That's great news. I want to get rid of the standard air box and replace it with the earlier type and believe taking the starter gives enough room to get it out.

Remove the two 'short' screws from the inner chaincase starter motor housing plus the outer chaincase screw immediately below them. The starter motor should then pull out.

I would sure like to see a video of that. I would think you would need to take the head and barrel off to get a MK3 air box out of the bike. I hope you can prove me wrong.

Hi Ellis. It's actually surprisingly easy to get the air box out. Take the carbs complete with manifolds and starter out. Drill the rivets out of the side panel bracket and remove it. Take the top bracket off the air box. The two screws on mine wouldn't undo so I simply levered the bracket up and pulled the screws out complete with the rubber nut inserts. Finally remove the two screws and nuts holding the bottom of the air box in. These were a right pain to get out on mine. Then it's simply a case of manhandling it out.

I refitted the Air box, without removing head and barrel, did remove the electric start, and probably also removed the carbs, from the head, Its is not an easy job but can be done.
