Look on pro circuits web site for a jetting base line, id say 260 main, clip in middle slot, stock pilot about 1.5-1.75 out, an snorkel removed from air box lid. If your pre mixing fuel then thats additional jet increase, an if your running high flow air filter an no box lid at all, thats also additional jetting increase. You buy jets from your local dealer, buy single jets its cheaper, id get 280-250. An a couple plugs for plug chops
