I just don't like when companies make "kits" for a bike they haven't touched. It seems to have a bunch of stuff in there but how much of it you would actually need is pretty questionable. If you want to know real numbers of jets we all use on our modified bikes we will tell you, they pretty much make it their black magic
What makes you think that they haven't tried the kit on a standard bike? Most kits are designed for bikes with OEM equipment that haven't been messed with. The various jets included in the Dynojet kits at least are for different elevations and in some cases they include additional jets for use with high flow air filters like K&N.
I don't know about our CB's but jet kits can be very helpful for bikes that were jetted lean from the factory. There are many examples of bikes that had less than optimum factory jetting to comply with emissions, meet better mileage targets, etc. Even many of the newer fuel injected bikes have less than optimum fuel/ignition curves programmed into them for the same reasons.
The Dynojet kit transformed my stock ATV by just following the packaged recommendations, no fiddling required.
