Our Keihin Mini-Main Jet Kit may be all you need. You get five (5) Keihin Main Jets of your choice, a jet carrier that can hold many more, and a jet wrench to simplify things.
You would pay at least $5 per jet at your dealer, and he likely won't have a full range. We do!
Retail value of this kit is $40 to $50.
Note that the color and design of the jet carrier may vary from the photos as we send what's in stock and buy from many distributors.
