i got a 02 2x4 350 rancher gots fmf pipe kfx 400 carb k&n airfilter would like to get more idea's on how to make more power and torque

That the problem with the Honda OHV motors they use on there Utility ATVs,there not much you can do to wake them type of low reeving motors up, unlike a higher reeving OHC motor. The why Honda Utiltiies have the lowest HP per cc in there class,unlike the Honda sport ATV which use OHC motor like everyone else.

The OHV motors make great torgue though ,thats why Honda uses them only on the utilitiy ATVS and in 2nd gear it feels like a ATV in low range.
