Jet kit help.

I have a stuck float on my carbs so I need to take them off to clean and I figured I might as well jet it while I'm at it. My question is which stage should I put in if my exhaust is opened up and I want to put just a filter onto the carbs?
Thanks in advance!

We ran that filter with a stock (leaky) exhaust using Keihin 108 Mains and 2 shims on the needle with 87 octane ethanol-free gas.

Pulled clean and strong the entire way, and spent most of its time over 10,000 RPMs.

If you decide to use a Jet Kit, use Factory Pro. They use OEM jets, unlike Dynojet.

Do you have a link to the stuff you used? I was looking at this all the reviews seem to be great and used on both styles of the 250

It's just a factory Keihin Main Jet, size 108, and 2 shims under the needle.

@$OUTHWORTH @Alex

Please don't double post in two different sections for the same issue, it's very confusing for everyone,

Oops, I forgot. Why do you need a jet kit? Just curious. I bought a 2007 this past March, I knew it was running lean. I simply installed 110 main jets and my bike runs like the hammers of hell. Do I need a jet kit? Maybe I'm missing something.
