I was on my way home a couple days ago, and the bike started overheating a few miles from home. Steam was coming from everywhere, up under the fake tank. I got it home and parked it in the yard. This afternoon I pulled the sidecovers, seat, and fake tank, and everything under there was covered in antifreeze. The reservoir was empty. I removed the radiator cap and didn't see any coolant. I started it up, filled the radiator and reservoir, let it idle a bit to get any air out, and put the radiator cap back on. I let it sit there and idle for almost an hour while I did some yard work. I heard the fan coming on and going off, the temp gauge never went above 6 bars. No sign of a leak. Could it be the thermostat stuck? I'm afraid to ride it anywhere for fear it may happen again.
