| Has this only just happened? Had you done any work on the bike before it started doing this?
If it's not the choke then check if there's any slack in your throttle cable. There is an adjuster at the handlebar end . Undo the lock ring and adjust the cable so that there is a small amount of slack in it. Don't forget to re tighten the locking ring.
If that doesn't work follow the route of the throttle cable to make sure it's free to move and is not getting snagged on a bracket or something.
