Hope you numbered the crank case shells and they have to go back in the same place.

Take the gear selector drum out and you will have room to remove the cogs ;)
You don't have to take the drum apart. If you remove the natural switch (that is under the engine) the whole drum will pull out.

Yep that was the badger! Started the cleaning process today.. well tried too. Went out looking for degreaser and ended up buying 5L of holts brake cleaner for £11 thinking it would do the trick.
Sprayed the crank cases liberally, left a few minutes and then blasted with a pressure washer annnnnd nothing happened. Despite the stuff cutting through the crap like theres no tomorrow its so volatile it just evaporates which solidifies all the grease again before you can even wash it off. Tried in the sink with some hot soapy water which again didn't really do the job, the only thing which did work was spraying small areas at a time with the brake cleaner and wiping it down with a paper towel. Took ages to do the bottom case but eventually i got to this:
Still needs a bit more work but got the worst of the grime off. My local motor factors also stocks Gunk and Jizer, would either of these fit the bill better (i.e. apply, agitate with brush, leave, power wash off)?

I've read through this previously and I don't think I can afford £2k of acid right now. Good to see how it's done on a commercial level though. Been thinking I may even not paint the engine at all depending how well it cleans up, I quite like the patina in the aluminium parts..
I've bought an m20x80 bolt which I'm going to grind the end down slightly and use as a rotor tool, are there any decent life hacks out there for the clutch tool? Pretty expensive to buy!
