Hi all, in need of some help.
I think my clutch is on the way out but it’s not acting the way I’d expect it to.
So I thought I’d tell you what’s going on and you could tell me what you think.

1st - When stopped at traffic lights it’s very hard to find neutral, keep jumping from 1st to 2nd or 2nd to 1st, but if I turn the engine off it’s easy to find neutral.

2nd – When coming to a stop if I’m in 1st or 2nd it drags and it feels like the bike still wants to keep moving, when I do stop the engine almost stalls but wont. Engine runs fine if i stop in Neutral

3rd – When at a stop and in neutral, if I click into 1st the bike jumps.

4th – Happened 2 days after oil change, correct oil and filter used and dead on the max line.

I thought if the clutch was on the way out it wouldn’t move, thought it would just rev like my car did when it’s clutch went, but I don’t know how a bike clutch works.
Could it maybe be the springs or something?
What’s the difficulty in changing a clutch assembly on a scale of 1 to 10?
1 being easy like break bleeding and
10 being hard like getting a old Micra to run nicely.
