please help! my 250 sputters, bogs, and just wont go after 7-8k rpms!

I've got 2000 miles on my bike and all was fine till the other day when i was riding in all my ninja 250 glory. i came to a stop sign then to my surprise the idle range sunk to an extreme low. i didn't panic i just kept the bike running and went straight home.

it was late so the next morning i went straight to the auto store on the bike and it was still idling strange so i got some sea foam. i put in about 4 oz. and went home and checked the fuel filter and spark plugs. all was fine.

i went to get some gas and after i filled up i went for another ride to see how it was. right when the rpms reached around 7k it would bog hard, sputter and the bike was like it just wouldn't get any gas at all. and it did that in every gear.

this a few days ago. and since I've been checking it (since i don't have any shop dollars right now) and it seems to have gotten a little better. i mean it will reach normal speeds but i have to shift early or try to really gun it to get past that really choppy 7-9k rpm range.

any advice would be appreciated.

thanks-bert

my buddy had some what of the same problem a couple of years ago and he said it was the carb. I am not mechanicaly incline so I will say the little metal flap, was stuck and causing to much air to be sucked in. like I said I took him for his word since I have no idea about the workings of a bike.:luck:

i cleaned the carbs! now it runs like a champ.. but it idles at 3k and when i try to set the idle or the air intake screws below 2.2k it idles rough then peters out.

im so close yet so far-bert
