I got my son a blaster for Xmas. So I g some work on it befor I give it to him. I added a k+n filter, removed the air box lid, Boyesen reeds, and a toomey muffler with stock pipe, removed tors and did an oil injection delete. Where would be a good starting point for jetting. It had a 230 main, I was thinking 250 but looking for any input. We ride between 0 and 3000 elevation. Thanks!
