How can carb ice be prevented?
The principal methods of avoiding carb ice are to heat the incoming air, or to heat the carburetor body. Wes has experimented with heating the carb body with some good success. Intake air is typically heated by routing it past the exhaust pipes in an airplane, and the same method could theoretically work on the Ninja 250. No one has reported attempting to use this method. Carb heaters for the Ninja 250 are available, both in the form of electric heaters (there’s a cavity on the Ninja’s carbs for electric carb heaters), and engine-coolant-based heaters. Neither form is easy or cheap to find, and either one will require considerable work to implement on the Ninja 250. Wes spent a considerable amount of effort designing an automatic circuit to control his electric carb heaters. More information about this circuit can be found in this thread, as well as on the project page Wes put together. Further information can be found by searching the board for carb heater. This is an advanced project
