Kyajet is the (only) tool for setting up Keihin® carburetors (and similar) and gathering additional information about jets and needles. It provides a nice and clean interface, comprehensive needle data, several comparison possibilities and much more. A perfect companion for all drivers of such carburetors!

Use it to optimize your carburetor settings while on the road. Enter your current setup data and compare them with different alternatives to let your bike perform better.
