i'm going to put a few things on my stock one-speed puch maxi, and need some help with jetting. i will be running a 15mm bing carb, 15mm intake, high flow air filter and a stock exhaust right now. i think the jet range should be around 68-72ish? but i'm not really sure... any help would be appreciated! oh, and i'm on the west coast in the pacific northwest (i think altitude affects things too?) thanks!
