This winter I noticed my bike was not idling high when cold. Figured the waxing unit that adjusts the idle for such things was bad. Seeing as I don't get colder then 40* temps here, I wasn't too worried about it. But lately I've noticed the bike won't idle correctly at its 1300rpm. Usually it dips down to about 1000rpm, other then that it runs fine as always. Well the other day I was coming off the freeway, downshifting till I hit neutral and just coasted from there when the bike dropped to like 500rpm. I revved it up and it didn't help, instead the f'er just completely died on me. Hit the start button, its fires back up within maybe 1 rev, and proceeds to run and idle perfectly for the last 2 days. Keep in mind this happened after 15min around 90mph and in 105* heat, but my only guess is the waxing unit is to blame. Any ideas?

 

Probably not the wax unit. When they fail, the result is high idle. And the fact that it is intermittent, leads my thoughts elsewhere.

Mine did that once last summer too. Left the house, got to the end of the street, and bam.... Low idle then stalled. Started back up and been fine for a year now. Although, mine happened cold.

Try cranking the idle up just a pinch. Maybe the throttle plates slammed shut a tad too much. Other than that, check you throttle bodies for build up and soot.
