Mine in the last two weeks has been acting funny again during warm up.
I checked the IAC and TPS and they haven't changed.
There's two things happening...
1) As the bike is warming up, the IAC will inexplicably jump from one value to the next a couple of times causing the bike to stutter. This tends to vary in time from start, but usually happens shorty after the bike switches to closed loop.
2) For some reason, no matter how long a let the bike warm up... once I start moving, the IAC will drop below 30... near 20-25, until I come to the first stop. Once I come to a complete stop, the IAC will go back to 35 where it belongs, then never drops below 30 for the rest of the ride. This does not seem to have any relation to time or engine temp. It's not such a bad thing, except that when I pull in the clutch to come to the first stop, the bike has died on me from trying to idle at too low of a rpm.
Once the bike is warmed up, though, it's beutiful.
I will make a note, that the only real change I know I made to the bike in the last three weeks, is I've been putting a cheaper brand gas in the bike. The shamerock station I usually use closed, and I've been filling up at a "race track" brand. Today, I found a Phillip 66 and put that in it. I know where a Shell station is too, so I may start going to it.
