Just put 665 wiseco pistons in my prairie, had a unifilter, 03 airbox, cut snorkle, big gun slipon. Im using dyno jeys beacause thats what was in it and i have abunch of spares. KIt calls for 132 and 136 which is way to rich, running 120 and 124 wth neeedles on the 4th groove and still at 11.7/1 air fuel. Is this abnormally rich????From what i have been rreading it shoulf be good with these jets.
