My '05 speedy now makes a couple of uncharacteristic clacks when starting that reminds me of the time the sprag clutch was dying years ago. It was replaced in 2008 under Triumph goodwill with the updated sprag. Unlike that time it has not been started with a weak battery. Also unlike that failure the bike also makes a single clack when turning off the motor with the key. How would the sprag clutch be involved when the motor is shut down? Can anybody confirm if their drying sprag was audible at startup and shutdown?
