great price if you need new cams id recommend hot cams
got stage one just to see if they helped in the trails and valve clearance needed to be done anyways.i did both cams and already had pipe and carbs done so they gave a real nice power gain ,my 09 kx250f pulls the front tire up in 3rd easy now and kick starts better then it did before..no real extra work over what had to be done for valve clearance’s
