Hey all, I just put a dynatek CDI box in my 2007 Brute Force, carburetored, and it is awesome so far for the power. However, the bike switched from 4WD to 2WD like it is supposed to and will not switch back. Does anyone know if the Dynatek could affect this, or is this just a coincidence? Also, I changed the pilot jets to 40's, shimmed the needles .040 already and it backfires with a hard deceleration from a hard acceleration. Any info on this would be much help.
