    Hey guys. So I traded an old lawn mower and a tiller I fixed up for an 85 maxim. The previous owner had cut the air box out and put k & n pods on. I was curious what some of you that run pods use for your jet combos. Also curious to what the stock jet numbers are in the event I put an air box back on. I think I remember reading somewhere that the stock jets were 100 & 40 or 110 & 40.
