Bikeman or RK Tek big bore for 2011 800 pro

Just wondering if anyone has run either of these kits or what people have been hearing about them

I know a guy with the rk tek. He said its got more power but it does not make his stock 800 seem like a 440 in comparison as the website states. Hes also running the doo thermostat ($28 upgrade) runs 106 degress and no rpm loss in long hard pulls.
