These bikes have alot of potential, I took a 08 250sx and built a hoped up 300 out of it. The timing of the 250 allowed me to create (with a few other tweaks, compression increase, porting, exc) a bike that pulls harder off the bottom and revs through the roof like the 250sx. Best of both worlds.
VOHK performance in kremmling can do the conversion pretty quick.
Same guy who does the sleds for chris burrant.
I am an artist by heart, sometimes dirt is my canvas and the tire is my brush!
