I got a 87 exciter for 5 hrs of barter this summer. The fuel line tee was busted. Replaced it and it fired right up and it idled then. I have been working on the suspension this past few weeks. All of it was completely froze up. I started it up today and now it won't idle unless I put just a little pressure on the throttle. I'm not even moving the cable just the slide on the throttle. Is there tors switch in the throttle housing? Whats the fix?
