You burnt it up on the line. When sitting still, you have to stay ” off the clutch” with your throttle, or you can burn them up in a matter of seconds!! Also, if you have a habit of blipping a throttle while your on the brakes, cornering, that can burn one up to. If your touching the brakes, you have to be off the throttle!! I’ve never seen a weaker clutch than on a leopard.
