Dynojet or K&N jet kit
#5
They are not the same. Dyno jet uses their own numbering system. Just go to the shop and ask for a Keihin main, pilot jet in the sizes you need. It will save you money and you won't buy thinkgs you don't need. Post your air box mods and your elevationa nd I can help you figure out what jet to buy. Single jets and needles are only like 3 bucks. Don't waste you money on a whole jet kit. You don't need it.

On my old 400ex, I ran a WB E-series Exhaust w/a K&N, 155 main jet, the clip down 1 postion on the needle, and no lid. It ran good year round with that setup.
