Nice, 78k in 4 years is a lot of riding! Regarding the overheating, check the radiator overflow hose for cracks where it comes off the nipple just below the radiator cap.John, I bought the bike 4 years ago with 72k, so 78k are mine. Although now I'm having trouble with it running hotter than before. Never crosses the upper white line but it rides right on it till it comes back down. I think the water pump might be on it's last leg.
