Frequently Asked Questions

What does a breather kit do?

It manages crankcase vapors that would otherwise accumulate pressure and flood your carburetor, which causes hard starting and fouled plugs.

Will this fit my fuel-injected V-twin?

No — this kit is for carbureted V-twin motorcycles only. Fuel-injected bikes use different vapor management systems.

Is installation difficult?

Installation involves routing hoses from the crankcase to this breather unit and then to the carburetor. Consult your service manual for proper routing on your specific bike.

What's included in the kit?

The Mikuni breather unit and necessary hose fittings. You may need additional hose depending on your bike's original setup.
