Hi, i'm having a bit of a problem with my 91 F2,any help would be appreciated. Tonite after class i went to start up the bike. Started it up as normal with choke and let it warm for a minute or two. the idle begins to decrease by itself till the bike dies. i try to start it up again and it turns over but won't fire up. i let it sit for a bit and try it again and the same thing happens, it turns over but won't start. so i let it sit for another few minutes and try again, this time it sounds like it's starting a bit, it turns and i hear the motor start but die, it does this a few times. i let it sit again for another minute and try again, this time it sounds more like it'll fire up so i keep my finger on the start button for a bit longer and then as it fires up i hold the throttle on and it roars to life. i let it idle for a bit again with choke on and then i turn the choke off and she idles fine and i ride home with no probs. any ideas? the bike is stock except for a slip on. this problem has happened a few times in the past 2 weeks.
