Idle setting

What do you most you run your idle at? I've seen 1600 RPM somewhere but that seems high. I've run 1100 and it seems fine. I can go lower but the bike seems to have a very slight stumble at reving if I set it below 1000. Perhaps something I could get used to when launching from a stop though.

Running it below 1,000 or so may starve it for oil.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

1,000-1,100 RPM seeems like where I used to run mine, mostly at 1,000 though, didn't mind setting it up to 1,100 especially during winter Mos. for crank and run a bit...
Someone with the manual will chime in and give the nitty gritty on it, but I think you are fine...
Have a good one...Old Dog...

Yeah it's 1100 is standard. 1000 is fine too though. I don't get into splitting hairs. Anything. Below a grand it might randomly stall and as mentioned, it's not good for oil pressure and charging, although stock charging systems don't charge until 1500 or 2k I guess so that point may be moot. I do notice that my gauge drops if idling in traffic for a while. Anyway, you're good.

Think the manual says 1,100 to 1,250 rpms..... If not.. That's what I'd go with anyway. 1000 rpm seems abit too low for a v twin.

Probably right. I think I set mine once at 1k and it shook more and just didn't seem right.

Dunno...

Really depends on if youre running a stock airbox and filters. I never had either, and just had the "goat's horns" with mesh screens (them 2 rubber thingies off the carb intake). I was running around 1100 then...but...after installing pods and some air screw tweaking, Im comfy at around 900. With an 'open intake", if you take 4 fingers and place them over the throat, the idle increases.
It IS however critical to adjust AFTER the engine has reached optemp...adjusting when still cold is really useless. Also, wear and age of an engine will vary the rpm setting slightly (i.e. you usually need a higher setting for a worn/older engine). This doesnt go for just the VNs, but for all 4 strokes.

I run mine at an indicated 1000 on the bikes tach, which the book says is not accurate, but that doesn't matter to me anyway, I don't use numbers, I go by what it sounds like. If you have messed with the filters, your idle characteristics will be different. I found mine will not idle steadily at 1000 rpm with the pilot screws turned 1 1/2 turns out (the factory setting) but purrs like a kitty cat at 1000 when they are turned out 3 full turns. At 1000 rpm, it is running strictly on the idle circuit, and a lean mixture will cause an erratic idle. I have never had my oil pressure light come on with it idling at 1000 rpm, and as has been said, it will not charge at any reasonable idle speed. I have an off switch on my headlight high beam, so I can idle it without putting to much of a drain on the battery. I also keep it hooked up to a Battery Tender Jr. whenever it is not being ridden.

I am a motorcyclist, NOT a biker.

1000 always sounds high to me. The only other bike I've ridden ( other than the little 250's the state of California makes you train in) was a Harley. The Harley sounds as though its idling much lower than the Vulcan. A sub 1000 idle gives a lop, lop, lop type of sound similar to other bikes.
