Re: what are bad reed valve systems

Hi Bobby<br /><br />I can tell you how i experienced it.<br /><br />The motor gradually lost power running, in the time of 30 secs. Then it ran ok, but with little power ( mine is 2 cyl Crossflow, a 4 cyl will loose less power ) When i pulled one plugwire at a time and grounded it through an old spark plug, and started motor, i found it wasnt running on one cylinder at all. A compression test showed nothing wrong. JB lead me to the fact it was a reed problem, and he was right - one leaf broken, one chipped. When i turned it slowly by hand with ignition OFF, i could hear difference in intake sound too.
