Hello new here names Travis. I have a Kayo Fox 70 for my two girls. I used to race motocross as a kid and have always kept something to ride my daughters can ride well and the Kayo didn’t have enough to keep them happy. I ported and polished the pz19 carb. Ported and polished the head and put silencer and header on. Runs good. Wandering if doing the port work to the head if I should change jets or if I need a cam to get the most from my port work.
