Just driving home from work, *clunk* Then neutral light comes on, but still driving along Shocked

Pulled over, flicked through the gears, found neutral. Then went through, still same, when pulled up at home, theres a rubbing/whirring noise. Typical bike is having its MOT this month, anyone got any ideas??? Sad

The switch is stuck, just unscrew it from the engine, clean it up & put it back in... or just replace it. cheap as chips.

The switch has a spring & a ballbearing, the shifter drum has a bump on the end that pushes the ball down to make the light come on. I'm guessing it's either stuck down, or mullared. May have a bit of clag stuck in it, or the spring may have broke.
They're usually a 14mm head.

It's a piece of piss to remove if you have the right socket.. If I coud lay my hands on one quickly I'd post a pic of it but I'm not sure where they are buried ion my garage.. Smile

The wire will go on the pointy end, the other end with the ball goes into the casing. This one has 17mm head

Step one:
Take the one out of the old engine & make sure it works. Then you'l have it ready to swap... Wink

The test involves picking it up & giving the ball a squeeze... Shocked

It's not actually a ball, just looks like half of one. Usually copper.
