*Must purchase 2 sets for the Banshee if you want to do both sides.
A reed petal is a wear item, and as such should be checked regularly for signs of wear and fraying.
Reed petals open and close 144 times per second at 8,000 RPM, so it's understandable reeds can wear. If wear and/or fraying is visible, it's time to replace your reed petals to maintain peak engine performance.
Designed to replace the reeds on the V-Force 4 Reed valve only.
