98 big bear stock jet sizes
 
I have a 98 big bear 350 and I was wondering what the stock jet sizes were? I need a size smaller on the pilot jet but I'm not sure what the stock sizes are. I have been having problems with the low end throttle response. I have screwed the pilot screw all the way in and the atv still runs, so I'm thinking I need a size smaller pilot jet.

Thanks

I have a Big Bear/Moto 4 clymer manual. For 96 and on: 45 pilot jet with 2 3/8 turns out, 120 main jet, needle on needle jet should be 3rd groove from top. Assumes stock Mikuni carb. Hope that helps.
