I replaced my tires this weekend, and after putting them back on I decided to clean (kerosene) and adj my chain. After I got it clean I had it on the rear stand and put it in gear watched the odometer after 1 mile I put the chain wax on then ran it on the stand again. I was about to shut it off when my wife noticed real thick black (gear lube like) oil leaking in the area of the front sprocket cover. I shut it down took off the left fairing and restarted it, but this time I didn't notice any leak. I put it back on the ground and had my wife sit on it, in an upright position, so I could see the engine oil site glass and it was completely full of tan (fresh) colored engine oil. I change the oil about 200 miles ago and have checked it at least 2 other times and it was at the full line, so why is it over the full line today? Sorry for the rambling but I wanted to include as much info as possible.
