When I start my Switchback first thing in the morning it revs its ring out then drops back to around 1400 revs and takes 4 to 5 minutes to get to 1000 revs that's in the warmer months in winter it starts at 1800 revs then drops back to 1400 and repeats the above. My question is can I disconnect the auto choke with out stuffing something. Cheers

Thanks for replying I've had it in the shop and they couldn't find anything wrong. I thought the 4 to 5 minute warm up might be a clue. Obviously not for them. Could've had beers with the money spent. I'll trawl utube to see if I can find an answer there. Cheers

My 2020 Ultra Limited does the same thing and has done since new. It revs to about 2000 - 2200 rpm when cold and will slowly drop the revs. What I have always done is about 2 seconds after it starts, just pull the clutch in and let it go. It ALWAYS settles the revs down to a proper idle speed.

Hey Ultramick thanks for the tip gave it a shot did not work for me but worth a go.  Cheers

Try the advice from Retroman. I was having revs climb and drop around the 1400/1500 range while riding on my Fatboy. Googled it and found the same advice that Retro offered. I think I used MAF sensor spray a couple of times and it settled the idle down on start up and when the motor was warm. Google it and you will see what to do. I think I found the advice from and US Harley sites. 

Bugga.......... I thought I had the solution too !

gave it a shot no good still doing the high idle . The climbing rev problem i have never had . rev problem is only on start up .Cheers

that wee gizmo can be a chit to clean. Spraying the cleaner thru the plastic hose attached to the can up the wee holes in the throttle body throat. Bit of clean rag in the throat to catch the worst.

adding to retroman's advice, i clean mine occasionaly as well and works fairly well.i locate the iac port just inside the intake at 12 o'clock near the a/c body mating joint,can be seen and is fairly small id. .then spray a bit of throttle body cleaner in the bore up into the valve ....and something i learned,cycle the key while doing it, opens and closes the iac helping to move the crap  from the bore of the iac.reminds me i need to do mine again.cheers

Does it come right down to what rpm set at car
