Help slowing down the idle

[Morgantician]

My '82 is idling a bit fast and I want to slow it down. It's sitting at around 1300-1500 according to the on board tach (which I realize isn't totally accurate, but it's noticeably fast to my ear and I'd like to slow it down to a nice low rumble). I've obviously got the choke all the way out but I'm not sure what kind of adjustments I can make to the carbs and/or motor to help me out - I'm a bit of a noob.

For what it's worth, I've changed out the air filters to pods and chopped the stock pipes down to right below the foot pegs. I've made carb adjustments to compensate for the fact, but in turn it's sped up the idle. Help?

Thanks!

Dumb question, but have you turned down the idle screw?

Why do you have the choke all the way out? Choke is only for starting and warming up a cold engine.

Haha, by "out" I meant "in".

And yeah I've adjusted the idle screw but couldn't slow it down enough.

synched the carbs yet?
How many turns out are the idle mixture screws?

Double check and make sure you don't have any air leaks around the carb intakes.

If the idle won't slow any more with the idle speed screw all the way out, that usually indicates your carbs are out of sync. One butterfly plate has closed all the way and the other is still open a bit. Play with the sync screw between the carbs and you should be able to pull that idle down. On a synced set of carbs, if you back the idle speed screw all the way out, it should stall the engine.

Def a sync issue. My bike revved high and I found that the carbs were slightly out of sync.

Depending on the year 1200 or 1500 is the idle speed. If you try to run it much slower it can stall unexpectedly and won't chahrge the battery as well at idle.
