Do a proper leak down test to check for an air leak first. Then report back. 

How you do a proper air leak test?

I've seen lean running engines rev up on their own. Turn your air screws all the way in and back out 1-1.5 see if it runs better (can even go .5). Depending on weather extremes might even have to change jetting). If not, clean your carbs and check your bowl height. If still nothing change pilot. Just doesn't make sense assuming it ran before with those pilots. I'd check the airscrew and cleanup carbs first.

I did already clean the carbs and that’s why I didn’t think it was the pilot jet I never had a problem in the past. I will adjust my idle screws thank you hopefully it work.

Having a problem with my banshee idling. If I have to choke all the way out the bike idles fine but as soon as I put the choke in the bike revs up maybe somewhere around half throttle but as soon as I pull the choke back out it goes back down to idle. I have sprayed everything down with carb cleaner multiple times to make sure I don’t have an air leak which I don’t. My idle screws are only in a turn and a half. Should I mess with the air screw? Seems like I have a lot more smoke than normal coming out of the exhaust. I have a 270 main jet in it and I’m not sure about the pilot I can find out later tonight. Do I need a bigger pilot jet or move the spot on my needle I’m not sure. The mods I have are stock air box with pro design air filter and no lid, v force 4 reeds and fmf exhaust and stock mikuni carbs.
