I'm looking to get a colder plug for my X for summer riding here in BHC AZ. I went riding this afternoon it was 121 deg and after 30 minutes the engine started to tea kettle a bit and I had to let it cool down, not to mention I had to hide behind a hill in the shade. Anyone know of a cooler range plug? If not I will have to consult NGK, they really helped me to get my RM100 to stop killing OEM race plugs on the trail as the OEM race plugs were way too cold. But this is the opposite situation. OK I found it NGK IFR9H11 IRIDIUM. Boy that was a short post.
