Pwk38 airstriker/ 02 cr250

7/5/2016 11:16am
So i put way to many hrs on my 02 cr250. Had the top end done, then decide to go for it and do the pwk swap. Along with replacing the old delta reeds with vforce. Im having trouble dialing the carb in right, after the machine shop installed the rc valve upside down the top was much better but im stuck on the 1/8-1/4 throttle it hesitates but runs fine after. Ive tried air/fuel got it at 1 turn out snap the throttle and no bog. Still boggs around corners. The shop i got the carb from order the new jets as well for my setup. I have a 170 main, 40 Pilot, clip in middle position, i will have to check what needle i have in there. And thoughts, or advice would be greatly appreciated!

I am running a NEDW needle on the middle clip, 172 main and 42 pilot. Try bumping up a pilot size and see what happens.

Try a CEJ needle with the clip in the middle, a 175 main and 45 pilot. A #7 slide works best on the 02-07 CR250.

That CGK needle is a little to lean for your bike.

Both of the above setups will work just fine. Although I prefer the smoother power of the multi taper NEDW setup over the single taper CEJ.

At your altitude I am sure a 40 pilot is too lean. At least a 42.

It all depends on which needle he is using. The needle will determine which pilot and main will need to be used.

Last time I looked, there were several on ebay for less than $10.
