I put a jardine exhaust on my stock 87, and I'm looking into jet kits to compensate for the exhaust.  I was looking into kits from dynajet, they sell a stage 1, 3, and a stage 7 kit for the savage.  I'm trying to figure out which stage is the right one for it as the only mechanical mod is the exhaust, can anyone recommend or point me in the right direction? Has anyone used these kits before?
