Dragging clutch
Scottvincent:
Hi Phil
No, it’s just a smear of grease that I used to hold the gasket in place whilst I did a trial fitting of the clutch.
Thanks

I can't quite see the angle of the arm from that view.
Presumably you've adjusted as you described, touch screw in then back out a prescribed amount?
You can, for investigative purposes, just touch the screw down and not go back to give slack to assess it like that. It may be a route to run as such initially to bed the assembly in and then reassessment after a few miles. That would give the most lift possible with the components you've got.
On these, the clutch if you give it some hard launches to heat it up (no suggestion to do this, but illustrative) results in the clutch pack expanding and moving away from the lifter mech, so it doesn't promote slip but more that you can't release it fully. It's low risk to run it as suggested above as it won't ordinarily give a problem.
Worthwhile to try it and see what you get in respect of it dragging.

Hi Jedi
I adjusted the clutch as you suggested and went for an exploratory ride. The bike went into gear without a crunch but was wanting to be off by itself. It could be held on the brake. Within 2 yards the clutch was slipping so badly that no further progress was possible. Ignominious return to the garage! I reset the clutch, as per manual and tried again. The bike went into gear without a crunch, but again wanted to proceed with or without me. This time the clutch engaged and rode as I would expect it to. Gear changes were quiet, even into first gear, but I could not engage neutral when stationary. The bike would stall when held on the brake.
I think that it needs a good long ride with frequent use of clutch and gears.
Any thoughts anyone?
Thank you

Try going back to mineral or semi synthetic oil as if I remember correctly you are using GTX
