Does anyone have the 120v wiring circuit for a 93/94 Cafe Racer. I would like to change to 240v input here in the UK.

Can't help you on the diagram, but you shouldn't need one. All you have to do is change the outlets and the input plug if it's different. The US standard on that wiring is 600 volts. Going from 120v to 240v doubles the power carrying ability of your wiring. 1000 watts power draw at 120 volts is 8.33 amps. At 240 volts it's 4.16. Remember the volts/amps/watts relationship. Volts times amps equals watts. Volts divided by watts equals amps.

Many thanks for the info. At the moment I use a transformer I had specially built but it weighs a ton!! I am also going to replace the battery charger as I am only getting 11.4 volts. The replacement will work on a variety of input voltages so no problem there.
Many thanks again and I bet you are glad you are not paying over 11$ a gallon to fuel our beasts!

Kind regards
