I have an 02 Foreman and i put an HMF Exhaust and the jet that they sent me on. i adjusted the air/fuel screw to where it runs pretty good, but my question is should i have changed both the pilot and main jet? should i have adjusted the e-clip? I've also got a K&N filter on it. i can feel a little more power but the way everyone talks it should have been a little more power than what i've got. any help is appreciated.
