looking for the jet size in there? only one way to tell on a older machine, open it up and look, willing to bet its probably been changed out before. or are you looking for the type of mikuni jet to get? do you just need to replace them, are you jetting up or down?

I went to rocky mountain atv . com and found a bunch of difrent jet types.

for the 1996 sportsman 400 the main jet is a 210, the pilot jet is a 30, the clip is on the 3rd position, air screw setting is 1 turn out, and the needle jet is o-6 (480). i have the manual right here for my quad. i have it rented out from the library.
