Ceramic Coating

[bioDog]

Dude, my bike always runs at half, and very rarely the fan comes on, especially on a 27degree day.
Did you do anything else to the bike other than the coating, eg, remove radiator/replace coolant?
Sounds like something was wrong for the fan to come on so regularly before.
The coating really can not have made that much difference. Just be happy that its shiny, dont go giving it extra credit for dubious claims.....

I would think it would make a difference with the headers sitting directly in front of the radiator. My bikes fan does the same through stop start traffic on anything over 25.
