Hi

I put an iridium plug in my bike today and had an immediate improvement in power! Very nice.... I was advised cmcpo it does no damage. All good!


My question is can I run higher octane fuels now like 97+ octane with no damage to piston or valves etc? Will it leave bad carbon deposits in the engine after a while or will the iridium plug cover that? Any help will be appreciated. Cheers
