Vacuum guage?

[Pixie]

For people after ideas for the end bits to screw into the carbs I used a couple grease nibbles with the ball bearings punched out with a nail.

You can get hose fittings with the right thread for the vacuum ports on the bike from the supplier too.Usually M5 thread.

Could be that when the fan was removed a short was caused in the circuit.And when the temp switch tries to turn the fan on the fuse blows.
The fan socket hasn't been shorted out has it?

Yeah that's what I recon is the problem but I can't find the wires going to control the fan so I might have to go hunting some more.
