I had assumed the solution to cool it down was the extra meat and fins where the plugs are. I'm guessing if one was to experiment, it would be wise to stick with plugs in the same heat range.
Ah, that's a very good point. I had forgotten that the CB has 'spark plug seat cooling'. I've never heard of any other production bike that has this (?). Probably best to stick to the specs on the plugs...
