Ok
New filter came. Oil and filter changed. Bike started ok, and ran good after about3/4 mins of warming up.
Tbs need a balance, but I think I need 3 more tiny o rings on the adjustment screws, as I’m sure they may be leaking just a tiny bit as I can’t seem to balance them to within each other of themselves very well.
All in all, the bike seems to start and sound ok now. Revs pick up well on the throttle, and a quick spin up and down a near private road revealed the spline job works well and the clutch feels good. It really is as smooth as you lot say!
A new indicator relay and switches are on their way, and the front fairing is close to finished.
Hopefully, I’ll get it taxed and tested for May!
Thanks everyone for your advice on it all!
