I have a 08 525xc I can't get quad to start. If I get it a shot of starting fluid it will start and run as long as I keep throttle opened up if I let off it stalls checked TPS and it is where it has been, marked from KTM, I took micro switch out of throttle housing because I switched to Honda throttle cleaned it up thinking carb might of got dirt in it from last hare scramble yes also changed spark plug. Thanks for any help.

you need to push the micro switch in order for the quad to start. check around the forums there is alot of info about this problem.

Can you give us a little bit of info on the lead up.
Has it been since you changed anything, had an off, preasure cleaned the bike, changed fuels?

Since the bike ran on brake clean that ruled out the ignition system causing the problem. I would suspect a clogged fuel shut off, fuel shut off turned off or some trash in the carb.
