What is the best way to renew the throttle cable on a gasgas txt 280 pro 2004 please.  Got a rough idea, but would like, if possible, another point of view.  Or if someone could give me a link to a video showing how to do it.  Thanks in advance.

Before starting the bike be certain that the throttle closes onto the stop in the carb. Listen to it clicking when you let go of the throttle. Try this while you  go from lock to lock with the handle bars.   

Thanks guys, great help. All done now.  Thanks again for your help.
