Good To Know

Q: How often should I inspect the carbon fiber reed petals? A: Reed petals should be inspected every 15 to 20 hours of hard riding for signs of chipping, cracking, or loss of tension.

Q: What happens if a reed petal chips or breaks? A: A chipped petal allows the fuel-air charge to blow back into the carburetor, causing hard starting, bogging, and rough idling.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
