Yes he's just trying to rip you off. It's always cheaper to buy the individual jets than the jet kid because you'll never use everything in it.

I'm sure you'll probably need a bigger pilot jet along with the bigger main jet. Don't forget to richen up your needle too. I would do a little more research on what your jetting should be at before you go back to the dealer.
