Paul, I would highly recommend the whole enchilada for the best low down grunt. I did some beta testing too, and the full jet change with foam is the way to go. And of course, get the overflows too if you don't have em.
Steve, nice video again! My only suggested addition is telling folks they can insert the foam from the air filter access door as well as from the rear exterior. In my case, that is the only way I can do it because of my cruise control junk being in the way.
Do you think it might work to just let people chop up the foam and put all the bits inside the airbox and let the engine decide? Kinda like dynabeads??
