So after riding awhile and going over a few bumps at about 35-40mph, I've noticed that the throttle control is a tad loose making it tough to control over bumps or rough terrain. Like it has too much play..

Is there a way to minimize the play in the actual throttle control?

Your not pulling your clutch in at the same time are you? Unless the grip is loose on your throttle tube holding the throttle shouldn't affect your ride over bumps.

If everything is fine, I would suggest learning some off road skills, it will teach you good bike handling techniques and improve your road riding if not make you more observant.

Thanks, its not the BIKE that im having trouble controlling.. When I go over rougher roads, the twist grip feels a little loose, thats all. Just feels like it needs to be a tad stiffer..

The tension on the throttle is given by the throttle slide springs in the carburetors, perhaps they're weak. A long time ago, I seem to remember people stretching the springs to get more tension.

Your throttle is not slipping on the handlebar, is it?

How much slack is in your throttle cables? Should be no more than 1/8".

I think restricting the movement of the throttle with a screw is a bad idea. The last thing you want is for the throttle not to return when you let go.

If it is the throttle tube loose on the the handle bar, I have used thin brass sheet cut in strips to shim it up.

Or you can file the mating face of one or both halves of the housing.
