I've got an 07 drz 400s, and I've got an aftermarket pipe and K n' N air filter with the 3x3 cut mod in the top of the airbox. I bought a dynojet jet kit for it and installed the new needle and main jet and all, but that was for a stock air box, and mine is modified with the 3x3 mod. I've heard I should just keep the stock main (142.5) in it and go 4th clip down on the needle. What would you suggest with the mods I have for it? It almost feels like it's too lean really, just the general way and characteristics of the engine and all. Any help and input is appreciated! Thank you!!
