2011 KXF450 vs KXF250 ...

[Cactus Jack]

These guys actually KNOW how to race 4 strokes ... no coughin' , fartin' , splutterin' , valve bouncin' , floatin' or over revving the coit out of the motor while they're in the air ...

Yeah I know how to embed videos ... I just wasn't thinking when I posted 'em ...

Yeah Coolie , I cringe when I hear people floatin' their valves from over revving under no load ... LOL ...

Then they wonder why their engine grenades long before its time ...
