Hello Andy. Long time since we've spoken (North Weald about 2/3 years ago - you were there on your Seeley)

Don't know the answer I'm afraid but welcome back anyway.

matthewmosse:
can do that on the cb550 motors - not played with a 750 though

Spitfire:
Hi Andy, the answer is yes, drop the engine out, turn it upside down and take the bottom crankcase cover off this will give you access to the selecters and the drum. Haven't done it in years though the last time was the morning before my mate was setting off on a trip to France, had to fix it in his back garden !
Remove the engine side covers (generator, clutch, gearchange), points cover, points plate, gearchange mechanism. In fact just follow the engine stripdown but ignore anything to do with the top end.
Make sure that you get all the crancase bolts out, including the top ones.

Cheers

Den.

Jumping 5th is unusal its usualy 2nd or 3rd. Start by removing the gearchange mechanism cover and making sure the detentsrring(s) are in good order----they have to come off to pulll the case anywayso its not lost time
