Hypothetically (because I don’t have the money or time), would a Polaris Sportsman 500, or RZR 800 be better if I hooked a snowmobile engine up to the transmission? I am wanting a go kart with IRS and 4x4 capabilities. Could the sportsman or RZR hold up to the snowmobile engine's power (upwards of 140+ hp)? Could the secondary clutch of a snowmobile be swapped for the existing secondary?

 

anyone?... anyone?
