I just put in a Dyno-jet jet kit in my '07 Foreman with a K&N filter with an Outerwear. I also have a Supertrapp Mudslinger pipe and I jetted it 165 main (below 3K), clip on third notch down, needle, spring- the whole nine yards. I just took it for a spin and I can't notice any difference! Well, thats not true, it does not backfire now and boy is that carb a pain in the ass to get in and out! Am I missing something here? My dad's stock '05 would pull the wheels up in second, mine still won't! Granted it is a PS model with a winch and 26" Mudlites. Should I have gone 170 or what?
