OK, from previous threads, I have removed and sort of rebuilt the carb. I finally got the bike started, but now it idles funny. Starts beautifully, will idle at 1,200 rpms for a few minutes, then starts going up to around 3500-4000. I have checked the throttle, throttle body and choke, and they all seem to be fine. The bike will ride, but when you let off throttle to shift, the rpms will stay high and slowly drop to normal, causes a little jump when shifting. When the bike idles, and i rev it up, the rpms will stay high, and then slowly drop to normal again.
From my experience in trying to solve this problem, by plugging one of the holes in the bottom of each slide keeps the idle from hanging. A lot of will say this is caused by a leans a lean condition.
If you want to come by next weekend, we can drop my plugged slides in and see if that solves your problem. I would be interested to see the difference. Since I am not running a stock engine, my logic may be slightly flawed. I do have another stock motor but it is not setup to run yet. Also, I can balance your carbs as well.
Yup lean...open air screws... they set to 3 ... BTW you have 40 pilots in it ... if not put 40's, if its 40's open air screws 1/2 turn.
Cool.

When I rebuilt the carbs, I made sure I backed the mixture screws out 3 full turns. (tighten the screw till it is resistant, then backed it out) I can give it another 1/2 turn and try it. I'm not sure of the jet size, I didn't put the jet kit in. I do know that it is quite a bit larger than the stock main jet that is in another carb I have.

Pilot jet, not main jet... You can pretty much open the air screw till it is ~5.5 turns before its likely to fall out...
Cool.

Just let me know. Anytime after 1:30 on Sunday I am free.
If a carb works fine before opening but doesn't work as well after reassembly then one or two of the small parts may have been left out by accident. There are a lot of little parts (the type that fall off the work bench unnoticed and roll under the shelves) in a carburetor that it can work without but not work well without. If the problem doesn't reveal itself you might consider getting a parts view and taking an inventory of the small parts in the carb.
My '93' ran pretty rough when I bought it. Couldn't find the problem so I took off both carbs and compared the internal parts. I found a small washer missing in the left carb. I bought a new washer ($0.23), and the bike has run flawlessly ever since. I guess the previous owner has a $0.23 washer under the freezer in his garage.
