Hey, yea when i got the bike, i cleaned the carb and air filter, the carb wasnt bad, no vizable grit or anything. But the air filter... maaan, i had to clean it twice to get it all out. Oh, i dont know if everyone knows this or not, but when i clean air filters, i spray the cleaner on the outside, then turn it inside out spray it on, let it sit, and wash it out with warm water. But anyways, I went riding with a buddy of mine, he has a 01 yz 250. and it ran like a top. im going to rebuild the top end, so i know its fresh, and lube it and everything. Anyone else have any suggestions?? Thanks again
