My friend has a Warrior and he wants more Power, is there a kit like in the 500cc or something like that? Or what do you suggest for better power?

 

Four Stroke Tech made a 500 kit for a while,but lack of sales made them discontinue it. You can still get a 435 or a 446 kit that will really pick it up,and would be more reliable than boring out to 500,that big,you start to have reliablility problems.Get a hold of FST,or Powroll,and I'm sure several others make kits in the 400 range. For 1200 bucks,Alba has a stroker 400 kit that is supposed to be a torque monster and really puts the power out.
