After about 4 miles I decided to stop at the store to pick up a few things. As I entered the parking lot, I noticed it was idling at about 750 rpm. It slowly built back up to 1100 in about 5 to 7 seconds. I blipped the throttle and the rpms went back to 750, then slowly climbed back up to normal. It did it a few more times as I made my way through the the parking lot.

After 20 min. in the store, I came out and cranked up the bike and everything was back to normal. Numerous blips of the throttle and it settled right back to 1100 rpm. Same result for the few miles home.

I'm not sure what was going on, but I don't like it! Dodgy

look like the issues that plagues the EX models...except for the stalling...

after dropping did you blip more?
so, it did not stall on you when it was idling around that low 750rpm after a short blip?

No, I didn't try to blip the throttle when it was idling at 750 (assumed that would kill it). I just let it slowly climb back up to normal.

As for the battery theory, I'm running a 1.5 yr. old lithium battery. I checked it out when I got home and it's showing a full charge and the same resting voltage that it had when new. Load tested, it was well in the green zone.

My ride to and from work today was uneventful. I tried several times to make the idle drop, with no success. It ran perfectly.

The only maintenance items I'm aware of are the air cleaner. It's a bit overdue for replacement (by the calendar). I'll get to that this weekend and keep watching it.
