Seestheday-I have the stock 4-4 (I think it's HM420) that came factory with the 79K. Dynojet gives instructions also on how to rejet with their kits if you have an aftermarket or high-flow exhaust. Keep in mind that if you buy a kit you'll have to drill to a greater width the holes in the carb slides... I believe with a #14 drill bit. It'll be irreversible, but if you decided after installing it that you didn't want to do pods you can revert to a stage I/airbox setup from the stage III kit, which just means changing the secondary main jet back to stock and putting the airbox back on. According to dynojet, even with a stage I setup w/ airbox there's a measurable performance improvement over stock.

Lucky, I think you're right. My throttle cable just got changed and the free play was adjusted really loose, so when I was starting from a stop I sometimes wasn't giving it enough gas. The problem has resolved itself after decreasing the free play.
