Looks like you're spot on there. Will get one ordered.

I'm still having the same issue that caused me to take the bike off the road before Xmas though.
I took it out for a spin, about 8 miles, then stopped for petrol. It took 3 good pushes of a few seconds for it to start after filling up, which leads me to suspect that the plugs are getting wet due to either oil leaking past the pistons or because it's not combusting all the fuel.

This started as an electrical thread, if you are having starting problems that do not involve the electrics I would be looking at the carbies.

You may be optimistic with only a "few seconds" on the starter button when trying to start the bike. Suggest you just press the button until it fires up, only if there is no life after more than 10 seconds would I suspect there is a problem. Same applies to a cold engine using the choke although I find that left idles for a week or more can extent the start-up time. How long before it fires depends on a number of factors, how hot the engine is, air temp, how old the plugs are, carby setup, etc.

Ok, battery and charging system are all pretty healthy at the moment, touch wood.

But the rear brake doesn't want to activate the light now. I can see the spring that goes into a plastic unit screwed into the rearset, then runs up to a connector with two wires that in turn disappears into the loom.

Can someone tell me where to start checking please?

Assuming front brake makes stop light illuminate, then easy first test is to pull on the end of the spring that goes into the plastic unit (switch), if lamps illuminate then switch position needs adjusting.

If first test fails then unplug the two bullet connectors that connect the plastic switch to the loom and put your multimeter probes onto the wires coming from the switch. Set multimeter to ohms and pull the spring again, resistance should change from infinite to 1-2 ohms. If resistance changes then switch ok, problem is in wiring to the stop light. If resistance remains infinite then switch stuffed.

Pulling on the spring illuminates it, so could you tell me how to adjust the switch as well please?

Edit: worked it out, glad to get that sorted easily.
