Just curious how hot anyone else's machine gets. Last fall and winter my machine hardly ever got into the black hash marks on the temperature gauge (wish it had an actual temp reading!!). However, this spring I frequently get into the last two "black" marks. I put 27" Black Diamonds on it a month ago and wondered if this was putting the extra stress on the engine and causing the hotter condition. I plan to flush the radiator fins out tonight to see if that makes a difference. Any comments would be appreciated.
