im having a problem with my 200x when i turn it on and i try to rev up alot from when im on idle speed, my motorcycle shuts off i dont know what is causing this .. can anyone help me>?

 

I assume you have good gas. You may have gunk in the tank filter. My 250sx would run fine at idle but die as soon as I gave it any gas. The little screen in the tank valve was clogged up with gunk. If that's what it is, take the tank off and clean it out real well.

 

Try it with your gas cap off, the vent or vent hose may be clogged. Pretty silly but have seen it happen.
