Is it for real or a mistake, does the dyno jet kit really only come with a selection of mains,a 160 and a 165? What about the pilot jet, shouldn't it be changed as well? I've done the smog off(made my own plates,worked great) snorkel off,air filter ect. but found when i put the dyno jet kit in, it ran worse, so changed it back to stock and rode it like that last year. Now im about to put my new WB can and stainless header on, should I even bother with this dyno thing, or go with daves mods, or buy a different kit. I live and ride in the mtns of BC so elevation is up there, but heard that doesn't make much of a difference with four stokes, but I do know I need to re-jet after the exhaust mods for sure. I looked through the jetting forum, but got distracted so im posting, hoping for some info and direction.
