Banshee only runnin with choke on

[Bansheeman1121]

Went back to stock carbs from 30s mods are, moose stator, dyna fs programable cdi, 20 over, fmf ssts, someportwork, v force 2s, boost bottle, no lid with k@n filter belive thats it, mains are 290 pilots 30, needles on 3rd poisiton from top. Tors are removed, it idles ok with choke on runs ok with choke on but as soon as u turn it off wont take any gas with choke off. Bike ran fine a few days ago with 30s on there so im guessin problem is just in my jetting on the stockers, little improvment when i turned the air screws all the way out, would to big of a pilot really cuase it to run that bad? how do the mains sound? any advice would be great

My best guess is the pilots are very large, especially with an air box. The porting MAY like a large pilot, but not if it's minor.

 

I think you may have dirt in the carb blocking something as well.

 

Turning the air screws all the way out (past 2.5 turns) means the pilot is way fat...or, it's clogged up.

For the heck of it, put stock pilots back in. turn the air screw 1.0 out. Clean the bejezus out of the carbs with carb cleaner, a piece of wire...and get into all the little passages.

 

if it doesn't make a difference, just for the heck of it swap the Dyna CDI out with the stocker, if you still have it.

Then check the coil/stator/coil plug caps.

 

If changing the jets and cleaning the carbs don't change a thing, start looking electrical.

Sounds like a clogged pilot to me

now i've had a few beers so correct me if you think i'm totaly wrong, i'll accept it but i think your going the wrong way. you said the bike runs better when the choke is on right? last time i checked when the choke is applied it richens up the fuel mixture so by that way of thinking you need to add more fuel to cure your problem. you said that when you turned your air screws out nothing happened. last time i checked when you turn the air screws out it makes the mixture leaner so considering that it runs better with the choke on i'd have to agree with greg and check the pilots for clogging, if there clear i'd start fattening up the jetting. like i said, i may be thinking all backward but it makes perfect sense to my drunk ass right now and it cant hurt anything if your going bigger. i know my jetting with fmf gold series pipes and 2 into 1 k&n is 310 mains/ 30 pilots/ 2 turns on the air screw and 4'th clip down on the needle with stock carbs. if it were mine i'd bump the main's up and drop a clip on the needle and see if it gets better. worst thing that can happen is it runs realy fat but thats better than running lean...
