What am I missing? With a belt clutch and a RAGB, how do you get a neutral when your not depressing the clutch?

For the guys that aren't using centrifugal clutches,  in our club you would make a lock for the clutch pedal to hold it down so you can push the machine around like it was in neutral.

George- I know you said you are running a clutch cable- but I don't see any pedal. How do you engage, and lock the clutch?

I am runnoing a centrifugal right now. I can switch to pedal in about 10 minutes or less. The pedal has a hole drilled thru it and the pivot mount. I press the clutch and stick a pin thru it. Works great. I went with the centrifugal because I let others ride it and its easier for them to take off.

Mine is so close (56") belt I use just one pulley. It is also the tensioner when using the Centrifugal clutch.
