07 KLX250s Stock Jetting?

[Pfc_Buck]

I have an 07 klx250s with a uni airfilter and snorkel removed. I also still have the stock muffler and will drill out the baffle next month. My question is> What size main jet from the klx300 jetting kit should i put in so it runs the best with this setup? I'm at 770 FT ASL and will not be changing the head pipe or exhaust for about another 6 months since i havent the money and will be at army BCT in 1.5 months.

This is a good question. I would be interested in hearing some answers myself.

I would reccomend a 128 Main Jet, Stock Pilot Jet and a Koubalink Adjustable Fuel Screw... Hope this helps!

That sounds too high. its gotta be a 125 or 122??

From what I heard I would pop in a 125 and see where you need to be from there. Thats close enough if your lean you won't be TOO lean and if your rich you won't be fouling any plugs.

i just put the biggest one (128) and it runs great. oh yea i removed the top of the air box and torched all of the baffles in the factory pipe and welded on a 1.5" diameter pipe onto the rear. now she is wheelie happy. gearing is 12-44:ride:
