At the moment, my bike hardly gets over 65 oC even when fanging around. Only really after a long run through the country it climbs to 80 (operating temperature). AFAIK, the ECU only switches off fuel enrichment at 65oC, so I'm wondering if my valves are carboning up... Seeing as it's going to get colder now, I was thinking of blanking part of the radiator with tape. Any of you guys in colder parts do this?
