CB1100 Idle speed instability problem
I posted to this thread about a year and a half ago when my '13 experienced the low idle condition (700 rpm) for the first time on a hot summer day. Since then it had only done it one more time. Both times I turned the engine off and the idle went back to normal upon restarting.

This morning I took a cool morning ride (about 60F) to breakfast. After 5 miles on surface streets and 10 miles on the freeway at 75-80 mph I exited and noticed that it was idling at 1500 rpm. Unusual, as the bike was thoroughly warmed up. The high idle persisted through the next few traffic lights until I reached my destination. In the parking lot, I shut off the engine and restarted. The idle went back to normal and was fine on the ride home.

So now I've had both the high and low idle condition and in every case it has fixed itself by shutting off and restarting the engine. Not anywhere near as bad as others had been reporting, but something is definitely going on with the idle system.
