Well-this is my problem."forever"my bike has gone through the cold start function(except when warm).Okay.Recently,she stopped doing that.And the idle setting began to change on me.I would ride for a bit,or even warm her up.....blip the throttle.She would drop back down to about 500 rpms above the set idle position,then after 5,10 seconds,drop down to the set position.Also,I noticed that after she dropped to the set position,if I closed the grip more,the idle would drop again slightly(not much mind you).Almost imperceptible,but just a smidgen.Okay-I checked my cables-seemed okay.Reset my return setting,and my throttle free play.All good-no pressure anywhere.However,the other day I went out to start her.Turned her on,cranked the engine-no start.Tried this one or two more times,then gave her gas while cranking.Nothing-but the FI error came on at that point.I didn't know to find the code number,you have to push both buttons at the same time to display it.So basically,I lost whatever code was in there.She finally did start,with a very rough idle,but then eased out and was fine.But still,the hanging above the set idle.And it doesn't do it EVERY time I blip the throttle(at idle)-but it is occurring with regular frequency.I'm bummed.I can't figure out what is doing this.I inspected my cables as I said.Checked the routing,all clear.Took the throttle cables out at the hand grip,inspected-seemed okay,no dirt or fraying there.Checked at the throttlebodies,seemed everything was okay.Cleaned and lubed em-still,when I go to start her,she cranks and cranks but nothing,until I OPEN the throttle as I'm cranking,then stop,turn off,then turn back on,and hit the starter again-then she fires right up,acts like she "may"be trying to do the cold start,but never really gets to that point-idles a bit above the set point,then drops down gradually to regular idle again.(like she's doing the cold start).Changed the air cleaner-no prob.I haven't messed with ANY settings.Haven't unplugged stick coils or anything like that.She runs like crazy-plenty of power,no stumbling anywhere.Idle is smooth.I did remove the PCIII thinking that might be causing the FI error.Went to my friend's house,then for a ride.Was only getting 29 MPG.(as opposed to 36 before with the PCIII).I couldn't ride her like that,knowing something is definitely not okay.Went home,reinstalled the PCIII-went for a ride.Performance was definitely perked up(as before)but now I'm pulling 41 mpg-70,80 mph in 6th.ANYONE have ANY idea what may be doing this(the idle deal?).And also,WHY would the FI error come on while cranking her and applying throttle?I didn't smell ANY gas fumes when this was occurring,like maybe she wasn't getting any fuel.Yet the fuel pump is coming on at ignition.Any thoughts on this situation guys?The only thing that I've done to her recently(within the last two or three weeks,is add Techron to the fuel about three times-which it says you can safely do.Thoughts?I removed the flies in 07,so that's not the problem.Even with flies out,she still ran through the cold start.And ANY ideas WHY my fuel milage would suddenly jump to 40's?It may go even higher-she was hovering at 41+(average mileage display).NEVER had that kind of mileage before.I'm stumped on this one!Battery voltage at start is 13-14 volts.Riding is 13.9-14.2 volts.If she dropped in voltage while trying to start her,would that trigger an FI error display?I don't think my bike will start at anything less than around high 11's or up.She'll crank okay,but won't fire at those levels(11's).
