I have a 2002 S model and want to do the air box, jet mods and drill out the exhaust. (exhaust insert done, what is done is done). The air box seems pretty straight forward, just don't go too deep. My question is; why a dyno jet kit at $85 canadian when a couple of jets (150 main ,27.5 pilot) would seem to do? Is the Dynojet #3109 jet kit magic. I feel fairly confident around my bike until the word "carb" is spoken or I go near it. Thanks a lot for any input.
