has anyone jetted there kfx or z 400 .and if so what size.thanks for any help

 

who cares about jetting there kfxs or z they will be slow no matter what you need to get a polaris if you want somin fast

 

jay u dont have to alway dream.every time we race cross country i win for some reason. maybe the little polaris just cant hang with the green machine.keep on dreamin away.remember we have it on video tape.lol curly

 

I'm doing a Z rite now but just don't have hard numbers for you yet.

We removed the baffle from the exhaust and the air box lid. I use jet drills for the mains and when I'm done I size it up and buy the correct jet (saves on buying 20 jets) #144 is what I would start with and don't be surprised if you get up to a #150 in there. I have seen post of poeple doing the same thing and using a #165, but I don't know about that. When I get hard numbers I'll post them for you.

 

thanks for the infromation
