I feel like my sportsman is a lil lagging in the low end grunt as it is, high gear has a hard time sometimes climbin rock hills, up and over huge logs, etc. so i want that extra power, just lookin at the smartest way to go about gettin it if an exhaust doesnt do the trick

At 60 MPH I still had 500-700 RPM to go till redline but it wouldnt pull the weight up to that redline, Polaris already has the Fuel Injected Models running 95 percent max with fuel Injection, Now the carbed Models you can do alot with, get a Slip on Muffler, Rejet the carb and Index your Plug, Do some other small Mods and youve picked up maybe 4 HP.
