jetting for stock pipes

Well here is my current headache...I own the 95 900SS\CR with stock carbs, stock pipes, a k&n filter using airbox without snorkels installed, a stage 2 jet kit ( 144 main jet, fuel mix screw 3.5 out, clip is 3rd from top I think). Bike also has FBF cams and FBF pistons, which I'm not sure how that is gonna affect the whole combustion process here. I used to have Yoshi pipes and ran the stage 2 kit with a 150 main jet and a stock filter, and the thing pulled like a freight trane down low all the way to red....Now I got this out for first ride today and it has no power at all untill about 5k or so,gas was dripping out of the boot under the air box. Should I go back to 140 main jet size and what clip adjustment would be suitable along with air mix screw setting? I wonder what else I could be forgetting....

i wouldn't expect mufflers to make that big a difference to jetting requirement. i'd certainly try it as was before i rejetted it.

why would my airbox be all wet inside is what i am wondering also? Today I looked at the airbox while trying to start and the vertical cylinders carb is spraying into the airbox. I had just taken off the carbs and reset the idle and was fiddling around with different air mix settings. Damn thing didn't even start today, I tried from 2 to 4 turns out in half turn increments on the air mix and it never even popped. I moved the needle clip from 3 to 2nd from the top. So I'll be back at it tomorrow again I guess, any suggestions?

they often push fuel back up.

hasn't got a valve sealing problem?

Could it be a bad coil?

I got it running today again, the cam cover was loose on the horizontal cylinder. I can't believe I forgot to tighten those, the other cam cover was tightened, I must have got sidetracked in-between covers. I can't however get the thing to idle at all unless i turn the idle screw in a ways and then the motor is racing at 3k and when i try to turn it back out it kills. I haven't done a carb sync since last summer when I had different pipes on it, idle was tough to find then also, but I did finally get it. I wish there was a Ducati dealership closer than 120 miles! It'd be worth it to have this thing dialed in right about now!

Took the carbs apart tonite and cleaned and took everything possible apart. I found a plugged pilot jet,hmmm, I guess that's why it wouldn't idle. Now its gonna rain for days on end cuz this thing is gonna work good again. Now, I need a or 6!
