I have a 97 400 foreman i bought it this month.They had put a jet kit in it. When i got it home it acted like it was flooding itself so i droped the main jet niddle it acted better,i then dropped it all the way acted better yet.. but still once and awhile i'll get a back fire or at wide open it'll stutter. I think she needs a new main jet. Is this the problem?

why did they put a jet kit in it, does it have any aftermarket parts such as exhaust? if not I would put the factory jet back in it.

The only thingelse it has is is the K & N air filter.

put a factory jet back in it and your problem will be solved. needle should be on the middle notch and about 2.5 turns out on the mixture screw. I know the 98 foreman 400 has a factory #130 jet in it. It should be the same for yours, but not a %100 sure. The atv parts counter will be able to tell you.
