Engine Breather & Catch Can Kits

The Riva Racing easy to install catch can/engine breather kit eliminates power-robbing crankcase fumes and oil vapor from entering your Yamaha engine's air intake. Increases horsepower by removing the engine's requirement to burn relatively non-combustible oil. Also improves intercooler efficiency by preventing oil sludge coating that lowers thermal efficiency. Excess oil vapor is routed to our translucent catch can where it condenses and collects for occasional draining via integrated petcock valve. Features anti-slosh tank foam to control oil movement.
