Good To Know

Q: What are signs of a failing reed valve? A: Poor idle, difficult starting, and weak low-end response often point to worn petals, and inspecting them for chips or gaps confirms the issue. Q: Are new gaskets included? A: This listing is for the reed valve assembly itself, so verify your parts diagram for any gaskets or fasteners needed for the job.

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