silverbird1100 Posted August 22, 2007 Share Posted August 22, 2007 This is the strangest damn thing. Easily my favorite part of a FI bike is that it warms itself up. My bike when I start it up cold is idleing at about 1K instead of 1600. I doesn't die or anything but it's not doing what it''s done every single solitary time I've started it from cold since day 1. I put a new power commander in a few months ago but this just started 4000miles later. Quote Link to comment Share on other sites More sharing options...
rockmeupto125 Posted August 22, 2007 Share Posted August 22, 2007 Has the temperature changed a bit since then? Sometimes it takes the injection a bit to adjust. You might also consider taking your PC out of the loop and cold-starting as a diagnostic. Quote Link to comment Share on other sites More sharing options...
shovelstrokeed Posted August 22, 2007 Share Posted August 22, 2007 YOur wax unit may be failing but, I suspect, it is just the warmer temperatures in the morning causing this. Mine will raise the cold idle just a little on a 70 degree morning, around 1150 or so but then it falls right back down to 900 till the engine gets to about 170 degrees coolant temperature and then it picks up to normal 1050 RPM. On a hot morning, >85 degrees, no cold start at all. The wax unit controls the opening of the throttles, ECU controls the mixture based on inlet air temperature. If the bike is sitting in the sun, the inlet air temperature could creep up enough so the motor will be a bit lean for ideal running when it is cold, that will drop the idle RPM.

silverbird1100 Posted August 23, 2007 Author Share Posted August 23, 2007 I can't see it being the weather since I've had it for 5 years now and it's always idled above 1500 for at least a 15 seconds. What worries me is if something were failing, it wouldn't start at all, like a carbed bike, right? And how do you get a new wax unit?

shovelstrokeed Posted August 23, 2007 Share Posted August 23, 2007 Started mine after an overnight sit, air temperature was 81 degrees. Idle was at 1200 RPM and gradually went down in <1 minute to 950 or so and then, as the motor fully warmed (a couple of blocks) it returned to 1050. So long as your bike is starting, I wouldn't worry over much about idle speed. Only time I have ever had cold idle as high as 1500 was the day I bought the bike. It was about 39 deg outside. Remember, this isn't a choke, just a fast idle device. Fuel mixture is taken care of by the inlet air temperature and coolant temperature sensors along with the MAP sensor. Out of curiosity, what was the temperature when you started the bike? Quote Link to comment Share on other sites More sharing options...

It ALWAYS ised to idle high when starting up. Something is different, I'm positive Quote Link to comment Share on other sites More sharing options...
MrBadExxample Posted August 24, 2007 Share Posted August 24, 2007 How many total miles on the bike? Does it still have the original spark plugs or air filter? Quote Link to comment Share on other sites More sharing options...

Sounds like it is fine now. You'll have to wait for cooler weather to see if the idle speed comes back up. The way the unit works should cause a variation in fast idle with ambient temperature. The colder the temp, the higher the idle. It should not ALWAYS go to 1500 RPM. It certainly shouldn't even come into play if the coolant temperature is at 228 deg F. Mine backs off at about 130-150 deg coolant temperature, sometimes a bit earlier if the ambient is high. Quote Link to comment Share on other sites More sharing options...

I can't see how that's possible since my 600RR, 929, 954, buddy's CBR1000 and Dad's ST1300 and Goldwing all do it the way mine used but not any more.

shovelstrokeed Posted August 26, 2007 Share Posted August 26, 2007 So go buy a new wax unit and install it. There are procedures for testing in the service manual, check them out first. I'm in Florida, you're in Colorado, might be a slight difference in climate. I have no issues with mine and it works exactly as I described. The GW is carbed so a different animal.

tomek Posted August 26, 2007 Share Posted August 26, 2007 I have the same problem,it has happened before,was just stuck.I don`t really remember what I did to fix it as it was many years ago.Lubricated/cleaned some rod I guess. I`m gonna investigate the problem tomorrow,so just relax and wait. BTW,it`s funny,mine started doing that while I was in Colorado. Quote Link to comment Share on other sites More sharing options...

Cool, if I decide to buy a new one, what's it listed as in the fiche? Quote Link to comment Share on other sites More sharing options...
tomek Posted August 27, 2007 Share Posted August 27, 2007 Throttle body,part # 8.That what it looks like. I`m dragging my ass out of the bed right now,,,,,,,,,I might just needs to be taken apart and cleaned,,,,,,,,, Later. Quote Link to comment Share on other sites More sharing options...

Thanks and let me know Well,better late then never. I finally got it fixed.I was gonna take a picture,but,of course,battery was dead.Murphy`s Law never fails.Basically it would be part 16 with everything that goes into it. There is a rubber booth with wire clamp,slide them both out of valve`s body,grab that small rod with pair of pliers and try to move it back and forward while spraying,let`s say wd40,on the part of rod that goes into the valve.Replace the both and clamp. That is it,it should free the rod and you cold idle speed will be back. Quote Link to comment Share on other sites More sharing options...
