Tear-Down

I started taking things apart today on the GB and I got more excited as I realized how easy this bike is to work on. I'm accustomed to working on sophisticated modern sportbikes so I revelled in the elegant simplicity of this old air-cooled single.

carb easily removed

rear wheel, seat, tank and side covers are off

Those side covers are steel. A nice touch of quality. The shop manual was included with the bike.

Mikuni slider carb that was installed. I have the original as well. I'll have a look at the floats and the gasket to see if I can find where the leak is coming from.

Sliding throttle valve. Airbox (sans snorkel) can be seen behind
