Thanks for your appreciations. To answer your questions:
The swinging arm caps are back on now, I forgot to put them on after I'd finished cleaning and took the bike off its NWS stand.
The Remus cans are properly E marked and not too loud, I'm sure they will be OK for the MoT but haven't had to try yet.
The small bobbins did save me a lot of damage in a low speed off in a slippery car park but I wouldn't expect them to help in a big off.
The seat was done by
http://www.motorbike-seats.co.uk/ I can't recommend Melvin highly enough. His workmanship is first class and the seat cost £240 including a Gel insert and postage.
Sorry I haven't got a head on shot showing the indicators, I'll try and take a picture at the weekend and post it.
