I just put on a FMF Powercore 4 exhaust on my 98 300EX. Today I got time and installed my jet kit. Everything went good putting it in. I used a Dyno Jet 128 main jet, didnt touch the needle or the pilot jet and I ride at 1000ft. I also didnt mess with the mixture screw that it said to adjust. I did adjust for idle tho. Well my question is did I use a big enough jet for the exhaust I used and the UNI filter I put on?? Also what is a good way to find out if you have your jetting right? Should I of adjusted the mixture screw? I did ride it around the yard a couple of times and seemed to run good. Didnt backfire or anything. I just need someone to tell me I did everything right. Thanks and sorry if this has been asked before, sort of new to the whole quad thing. Any input would be nice. Thanks Jake
