Default adjusting Idle

hey everyone I am having a problem with a 1993 xlt sp w/ a 580 tripple that after warming up the sled Idles at a very low rpm and wants to die all the time . my question is how do I adjust the idle speed ? when I first start it, it idles at around 1200 rpm,then when its been going for a half hour or so it wants to die unless you manually feather the throttle.

You should have an idle adjustment screw on each carb or if like my sled I have one that adjusts both carbs.
I'm not real firmilier with tripple's but some one on here will have probably a better answer than me.
But you should have the adjustment screw there somewhere.

The large screws in the side of the carb's (the ones with the springs on them).
Turn them each in a 1/4 turn at a time until the engine will idle at 1800 rpm when warm.

Before I give any advice, I'd like to know if the sled has always done this or if it's something that recently started?

The reason that I ask is if you have another issue causing your idle to be so low, cranking in the idle screws will only be "fixing" a problem caused by something else.

madcow rebuilt the top end and replaced the needles and seats and cleaned the carbs....the sled runs great but after warm up it wont idle. so I assume its just needs an adjustment.

Ask Madcow if he cleaned the pilot jets with fishing line or strands of wire. Idle to 1/4 throttle is your pilot circuit. I would make sure those pesky pilot jets are clean before doing any adjustments.

If the needles and seats are replaced... A very common problem to have go wrong on the XLT Id say that this is a problem with the adjustment screws... Its sounds like its getting too much fuel maybe and is flooding itself out when its warm... This sounds like a loading up problem to me.
