Hi I have a YB8 in for servicing and need some info on the fuel reserve switch.
Is reserve on when the light is on and main tank when light is off?
Also chrome rocker switch next to light switch l/h handlebar, what is this for?
Thanks Andy

The main fuel tap is permanently set to on by the lever on it. When the part of the fuel tank that the main fuel tap draws on is exhausted, the push button on the dash can be pushed until it illuminates, which activates a solenoid fuel tap which accesses the fuel in the tank that is not accessible by the main tap.

There wasn’t a chrome switch on the handlebar when the bike left the factory, so I don’t know what that does. But if I was to speculate, I would say that the dash reserve switch has failed and given that they’re no longer available, a previous owner has installed an alternative way of actuating the solenoid tap.

When the fuel level drops, the low level switch drops out on one cylinder to let you know you're going to run out of fuel, and the light on the dash comes on. You press the light to acknowledge the need for fuel, and the bike goes back on 4 cylinders.

Thanks Guys.

I'll pass this onto the owner when he collects the bike.
Very helpful information.
