This goes on before the arm

Well that’s a pain!

Also attach the brake rod to it, not easy to get the pin in and the split pin afterwards  ;)

All sorted now. Spent ages trying to crack it with the swingarm still on but it’s impossible to get the spring into place so had to strip the rear end back down like you said. Made some good progress, both wheels on, both brakes on, bars internally wired and installed. Hopefully can crack the electrics today.

One thing I’ve noticed is there’s a reaaaally tight clearance between the swing arm grease nipple and the little bracket for the carb bowl overflow tubes at the back of the engine



Ive purposely bent the bracket to allow enough clearance there, it’s not the original grease nipple as that one snapped a while ago when it hit that bracket when installing the swing arm for the first time! Have I missed something here?

I found this out the hard way.....although not impossible it is a pain in the arse.

Had some slow progress today with the wiring. Basically all I’ve managed to achieve is an oil pressure light and a gurgle from the horn. Tried the horn directly onto the battery and it’s plently load which makes me think it’s a ground issue. The frame ground is bare metal as I’d already sanded it back. I haven’t sanded the frame on the engine ground as I didn’t think it was needed. Seeing that the switches ground through the handlebars should I be removing paint for this? Only one of them (left) has that drilled locating tab.
