Thanks jerry.skipro3 said:I don't think you should need to totaly remove the airbox lid or drill the extra holes for a 125. The U.S. version 200 and 220 engines probably pull in a bit more volume of air than a 125 and the mods would help out there. I would try a couple of test runs without the airbox lid to see if you notice an increase in performance. If you don't, then pop it back on. If you do, then start by drilling 6 holes and again test to see if there is a difference between no lid and one with 6 holes. Soon you will find a point where no more holes make any difference. In the case of U.S. model bikes, that's about a dozen. (12)
Good luck and have fun learning with your son how to maintain and feed a dirtbike. It will be a great experiance for you both if you let it bring you closer together.
