Not alot you can do with the Honda Utility ATVs, there the only ones that use the low reeving old school OHV motors. Its the reason Hondas 4x4s are the lowest rated HP per displacement vs other makes.
They do not have the mods available like the OHC motors found on other 4x4 ATVs and Honda's sport ATVs.

The Hardcore Mud ATVers that use Hondas do use gear reducers when they up there wheel sizes rather then look for more motor power.

Here is a TRD GEAR REDUCTION HONDA 420 RANCHER SRA & IRS 07-10 & HONDA 500 FOREMAN (05-12)
