Now that i got your attention. I heard that taking the air box lid off my kfx 400 and re-jetting would give me about 2 extra ponies through out the power band. Well thats great but i don't know what jet size to use. I'm at 2800ft. I don't have the money for a pipe right now so don't bother telling me "if your rejetting go ahead and spend X amount of dollars on a pipe" trust me if i did have the money that would all be taken care of. Any imput would be nice. Thanks.

 

i'd go up about 2-4 sizes from stock...then do a plug chop
