I have a 98 MXZ 500 LC in the shop here, and wondering what the stock jets are? Also how many sizes to jump up for UNI Pod filters instead of an airbox? Owner lost the box, and he has pods on it now. I have 350 in PTO side, and a 320 in Mag side. The motor was just bored .20 over W/ new Wiseco Pistons. Any help would help. Thanks.
