Starting from a stop without pedaling?

[stangkid]

Is it actually possible to not pedal off from a start, when your motor is already started? just using clutch + gas?

Yes it is possible.
Things are even easier if you install a centrifugal clutch:

I do it all the time without a centrifugal clutch. don't just dump the clutch and it should be relatively easy

Depends on the gearing, don't expect it to be easy with a 41 tooth sprocket. I run a 48 tooth, and start from a dead stop with ease. Don't expect your clutch pads to last as long, however, they are cheap and easy to replace.

I do it with a 40 tooth and a 200 pound rider on a 70 pound bike.
