Hello. I'm new to K100s. Just picked up an original owner '88 K100lt with 20k miles. Great condition bike. I went through all the maintenance items before firing it up. Had to install a new starter relay because the old one was fried because of a weak battery. The bike fired right up and everything worked well. I went on my first ride...
A few miles from home the horn just started blaring. I pulled over and tried shutting the bike down. Horn kept going for about 5 minutes then stopped. I started the bike and went home. Same scenario happened again so I pulled the horn fuse so I could get to work.
I've looked at many posts and I can't find one with this unique problem. Horn decideds to come on and go off on its own. Any suggestions?
