I had a similar issue on an old bike, the clutch arm operates like a rack and pinion, the arm being the pinion part. I had to engage it further down the rack to get the full range of movement. It's spring loaded, I hope that makes sense lol.

Looking good

@Louis-James hmmmm

@Louis-James another thought, is the light in the clocks led? Try disconnecting that if it is

@Calum definitely transforms the bike. Changing the gearing helps as well, I'm 1 tooth smaller on the front sprocket. Revs really nice now. Might get around to the zeel one day

Definitely 4 in mate, and 3 out. I put a ring terminal on mine and earthed to the frame. Same thing. Black with a green stripe

If the lamps are standard my money is on the relay. Try disconnecting one and see if you get a flash then.
Is the switchgear new?
