hello, im searching for long time for HOT CAMSHAFT for ex300
anyone know where i can get if its exsit ? or my other atv hot cam will fit ? + what other upgrades i shuld put for it to work smooth
thanks alot

 

Hot cams does not make a cam for it. Web, mega cams, White Bro's all sell cams for the 300. If you go much bigger than stock, you'll have to get harden rocker arms. Other parts that go well would include a higher compression piston. Bigger valves, stroker cranks and big bore kits. Porting can have major effects also.

 

i thought is was a 300ex........

 

what?
