well.. heres my problem...
I cleaned my filter, and everything seemed to be ok... two weeks ago...
didn't do anything to it after that besides just hose off the dust and put the tarp over it.

I went to croom last weekend, and it ran like crap.. when I pulled the plug it was BLACK. so I pulled off the little cover I have over my filter, and it still didn't run real well... I went down a stretch and cut the engine of at around 3/4 throttle, and when I pulled the plug, it looked ok, but it still was hitting like a rev limiter or something around 3/4 throttle, and wouldn't go WOT... lower rpms ran great, but if I was at idle, and I NAILED the throttle, it would die out, but if I rev it a little slower from idle, hitting it, but not hitting it fast, it woud rev ok... seems like it only bogs down when its under a load, and then if I nail it it just pops once and then it will die... theres no way I have to clean the k&n after EVERY ride for it to run decently is it? (this is all in nuetral when it dies when I nail it by the way)
