I got a call from a friend of mine last night with the same issue. His will start good and after about 2-3 miles it will shut off. He tells me he can let it sit for a minuet or two, starts up and it runs fine. He tells me that if he stops somewhere for a while and the bike cools off, it will do the same thing again. He does get some backfiring also.I have a 1986 GL 1200 that will just sop running at highway speeds. when I pull over it will restart but might back fire now and then before it restarts. any help out there
Welcome to the Forum. The pulse generator coils located behind the timing belt cover are fairly notorious for killing an engine when hot. But don't generally allow a restart until cooled off for 20/30 minutes.
You can download a manual for your Wing from the Ref/FAQ section to further help in your trouble-shooting. It sure sounds like ignition problems. But you may also want to chech-out the fuel delivery system.
Check back, as your sure to get some more responses... :gunhead:
I agree with Shooter. I remember the GL1200 LTD's were notorious for having the pulse generator problems. I noticed you have an Interstate but it still could be the problem.
