Throttle sticking open - SV650.org

Hey people, I have a problem with my 04 that is really annoying me.

If my bike is cold, it runs perfectly fine.

Once it gets up to operating temperature though the throttle will stick wherever I leave it and will not close unless I twist the grip closed, this does not seem to be related to the throttle cables at all, they look like they're in good condition.

I've taken the Throttle bodies off and cleaned them thoroughly, there was nothing in them that I could see that would cause them to stick in any way and right now I'm getting close to stumped, does anyone have any ideas?

well nevermind the problem, I identified it: the radiator hose is very old and is severely expanded, it got to the point where it was expanding under the throttle actuator and causing it to first snag the stop and then pinch the entire actuator causing the whole thing to stick open. New hose will fix problem
