310 jetting?? need help

[LT250Racer609]

ok in the early spring i put a 310 kit on my 250r. When i did that, i had a 200 main jet in and a 45 pilot. I have a 38 mm air stryker carb. when i had the 200 in it in spring, it ran nice and strong all throught the power band. Now all of a sudden (i think its cause its hotter and the humidity) about half throttle it starts to bogg and if you pin it, it boggs even more. Now the spark plug is always soaking wet after it does this. So i put in a 182 main jet and it got better but still bogs after half throttle. Do i need to go even leaner???

I ride at sea level and when I had my 310 with 38mm air stryker I think I ran a 168 or 170. Hope it helps.

I have a 310pv in my atc250r, cr igntion, 39 pwk, and pt pipe. I have a 170 main, the pilot and needle that came on the pwk carb. the plug is exact on the color it should. I think my needle is on the 4th clip.
