Idle air control disconnected

[steve]

I disconnected idle air solenoid,have vance n hines baggers,KnN open filter,cobra 2000 FI,first time starting bike since disconnect,would not start,pulled out choke which got it to start,never had to use choke even in 30 dgr temps,any ideas,2004 Nomad 1500,thanks

You disconnected the idle solenoids? Did you plug the vacuum lines? The bike will not idle as well when cold without the solenoids but it shouldn't be hard to start.

[steve]

Yes because they click loud and annoying,after a few min of running it started fine and ran fine,just dont no why it was hard to start,I pulled off wires,left solenoids in place,left hoses connected plugged upper openings on solenoids, Thanks for your input,I didnt think it should have have been hard to start either.

[cactusjack]

After I removed my solenoids, I'd have to use the "choke" (it's really a fast idle knob) for about 30 seconds or the bike wouldn't idle smoothly and die. It was never hard to start, though.

Have you cleaned your throttle body? Use an old toothbrush and some Seafoam or spray throttle body cleaner in both tubes and scrub them, also scrub both sides of the butterfly valves at the back. I used to do this each time I changed oil.

Steve, on mine (no idle solenoids at all), the first time I start the bike for the day, I have to pull the "choke" to get it to start, even in the summer time. After the first start-up, it will start fine the rest of the day. The job of the idle solenoids is to make the bike start and idle when the engine is cold. If you remove or disable them, they can't do their job, so you have to compensate with the choke.

Recently cleaned throttle body,I tried a few times without choke,once I pulled out choke it was ok,so Im guessing when without solenoids you have to use choke after it sits for a day.

[blowndodge]

Yes you will need to do that.

Thanks everyone for your help

The enricher (so-called choke) on mine has been disconnected for years.

It starts fine with a little twist of the throttle.

I never have pulled the so called choke, but do hold a little throttle on a cold start. I don't have the solenoids on the bike at all. Warmed up I just hit the button.

I don't have to use the choke either to start the bike, but once it starts I do have to hold the throttle for a minute.

[macmac]

Not sure in real time, but just long enough to back out of the barn is typical for me to hold throttle. Pretty much I lock the vista cruise for that. Then I let the bike 'walk' out the 1/2 mile drive here. I can never have a spotless clean bike for that drive.

I don't use my fast idle knob for cold starts either. Just a slight twist of the throttle and lock the Brakeaway for about a minute and I'm good for the rest of the day.
