Rightly or wrongly I have ordered some more Irridiums to replace my last set which were one step colder than stock. I have the OE 108 kit with 10.25 pistons and understand that this combination needs perhaps even two steps colder rather than the one step I've been using.
My question is what would tell me that I have gone too cold and should go back to the one step colder. My bike really pings sometimes especially on hot days in the Rockies with the one step colder plugs so I'm hoping I may help this a little with the even colder plugs. Thanks:}
