i would like to know what jet sizes to run in my kfx 700 just put on hmf full system and k&n air filter. i am in utah about 4,800 ft does any body in utah have this set up or would just know about the right set up.
thanks for your input.

 

I live in southern Idaho and I ride at about 4000 to 6000 most of the time. Look at my pics. I took the snorkle off and replaced it with the top off a traffic cone. Sucks in air real good. I cut the baffle out of the inside of the air box. I put one 1 1/2" hole in the right side of the air box. I am using stock air cleaner. I am running with 152 f and 155 r main jets. The plugs are a very light tan color. It runs perfect and a very strong 72 mph. If I idle around a lot and check the plugs they look a little too light to me. I'm thinking of shiming the needles .020". I am running Pro Curcuit T-4 dual exhaust. LOL. Hope this helps.
