your pilot jets are what makes your machine idle. you need to pull them out and make sure they are not plugged. then you need to adjust your carbs. Do you have the T.O.R.S. removed? You also need to put the needle back in the middle.
Here is an adjustment sheet when you have the T.O.R.S. removed
first...with the idle screws completely removed, remove the airbox (makes it
easier to see and work on). Make sure with the idles screws removed both carb
slides fully bottom out and seat with no throttle. Then...slowly move the throttle
and make sure they move up at the SAME TIME.
You use the adjusters on TOP of the carb caps for the syncing of them.
Next, place each idle screw in. When it touches the slide, stop. Back it out,
turn it in, etc. Once it is JUST at the point of touching, turn that screw in
2.0 full turns, and lock it down. Do the same on both.
Check the sync on both of them again....
Put it back together....
Warm it up...and set your air mixture screw next. Start with the air screw
out .5 turns from the lightly seated position. Keep turning it out until you
get your highest idle, only go .5 turns at a time.
After you turn the air screw out, WAIT 20 seconds for the adjustment to take
place. When you get your highest idle, then...adjust it up or down with the
idle screws....
