HELP PLEASE!!! Air/fuel mixture screw?

[redexrider4290]

hello i am in desperate need of help! i used to have a HMF full on my 03 250ex. i had 125 main jet and air/fuel mixture screw turned out 2 1/2 turns. well now i need to get it back to stock. put back on exhaust and jet. but the bike won't idle?

i did still have to airbox lid off but i covered it and and it still didn't idle. i'm thinking that it's the air/fuel mixture screw?

does anyone know what the stock setting of the screw is?

jeeze dude, 125 main?

should be around 105 or 110
but are you putting the stock pipe back on?

in any case, read the sticky thread at the top of the 250ex forum, it will tell you all you need to know
