Yz250 starts but bogs and shuts off

I have a 2011 yz250 i use as a woods bike. I noticed the other day it started to get just a split second lag in power when i get on the throttle. I took the carb apart and the pilot was a little plugged up. I cleaned it out and even jetted it with a 45/172 to lean it out a little for woods. I rode it a day and it still did the same thing. Next i took the v force 3 reeds i had in out and put the stock back in just to see if maybe the reeds were going bad. I rode it up the yard and it bogged and shut off. It would start back up but only run for 30 seconds or so. I took it all back apart and put the vforce back in it and swapped out a few petals that were getting worn. Now the bike will start and bogs real bad and then eventually shuts off. When it shuts off it back fires almost every time. The plug is always wet when i take it out. I know this jetting isnt the problem because i have another bike with the same jetting. Also a slight adjustment wouldnt make it this bad. I tried taking the powervalve linkage cover off and it looks to be moving right but could there be something else with the powervalve wrong? Or any other ideas? Thanks
