The "Premium" 10.8lb Spring set is made of a high-quality wire for superior performance. This Premium spring will allow the engine builder to custom fit their spring to their particular build. Having been through a specific process, which will reduce the amount of spring pressure loss from running in the engine, this spring will allow the engine to run a higher RPM before experiencing uncontrolled valve float.
This spring is considered a "Builders Spring" and will not test legal without being set. Springs should be checked prior to installation to insure they meet rule requirements.
Valve Cover Gasket for the BSP Clone 196cc Engine. Will also fit the newest version Gen3 Predator 212cc engine with 27/25 valves and split keeper retainers.
