07 road king, pciii, v&h big shots true duals.

no issues for over 2 years. but recently have started having an idle problem. sometimes when i start the bike, the idle is high. no problem, bike is cold..... well, the idle doesn't drop in 15-20 secs or so, it just continues to be at fast idle (how fast, don't know, no tach, but would guess 1300-1400 rpm).

if i shut the bike down, and restart, most times, the idle will drop to where it is supposed to be. occasionally not, have to restart again and it will drop.

every now and again i wouldn't have an issue with this, but it is starting to do it more frequently. getting ready to go on a road trip and would like to have it resolved by then. not worried that its gonna strand me anywhere, just don't like having to restart to get the idle right.

 

anyone?

 

Yes, been there and done that. First, get a can of Seafoam injector cleaner and put some in the tank, a little strong. 2 take the breather off and look into the intake at 12:00 position and spray some cleaner there to make sure the Idle air speed motor isn't sticking. 3 oil the throttle cables good, that will cause it also. After all of that, the last thing it could be is the induction module seals or in my case a cracked induction module. It took 2 years and 24,000 miles before mine was corrected. I hope this helps.

 

sounds like the sensor in the top of the front cyclinder that controls the idle till the engine warms up ... I've had one go bad and had different idle speeds at stop lights simular to what you describe ... once replaced the problem went away and hasn't been back

 

thanks, will check those out

 

mine idles kinda like that,, i dont let it set there idling till it heats up( a couple minutes) usually , a quick twist of the throttle will make idle speed decrease... never knew one would be warmed up in 15 seconds (on a cold start)hot start sure

 

I had that problem on my 07 night train. Idled high (maybe 1300-1500rpm) even once warmed up. I could count to 10 seconds once I came to a stop and the idle would finally come down to mormal. I went a ride up Mount Washington in NH with it and had to shut it off several times because it wanted to run so high at idle.

when I finally had the bike dyno'd after putting on pipes and power commander the problem went away about 80-90% and only occasionally did it again. I traded the bike recently and bought an 09 electra glide classic so I could ride in comfort lol.

 

What should the bike be idling at? I think mine maybe high.

 

Not sure on the 07 but on the 08 with throttle by wire if this happens you will need to cycle the ignition switch (key) on and off 4 times to reset computer.

 

that is not what mine is doing. that is normal operation. unless i shut the bike down and do a restart, the idle will stay high, doesn't matter how long i run.

no, on the 07, i just have to shut it off, then do a restart and its usually fine.

i'm thinking that the first thing to check would be the idle air speed motor as per dgriffith. the temp sensor next, though i think that if it were bad, then a restart wouldn't reset the idle to proper range.

gotta get to autozone and get some seafoam. i think i'll go ahead and service the ac filter and replace plugs while i'm at it.
