Sudden Oil Consumption Sat Nov 09, 2019 11:58 pm

Today I decided to take a ride to make sure the bike was still running well. I am currently at college and try to run the bike at least one or two times a week to make sure it doesn't sit (also gives me an excuse to go riding through the Adirondacks for an hour or so). When I started the bike up it smoked a bit more than the normal amount, and I chalked it up to the temperature being around 30 -35 degrees Fahrenheit. While riding I noticed that the normal noises slowly, but continuously, got louder. When I parked the bike I looked at the oil sight glass and saw nothing. While riding I did not have any idiot lights going off, I was monitoring it closely since the noise was up from what I normally have heard. I checked 30 minutes later (to give it plenty of time to flow back down) and found only a small amount at the bottom of the sight glass. Looking through the oil fill hole I could only see a tiny amount at the bottom of the case. I always check my oil level before riding and today it was about 2/3rds of the way between the middle dot and the top of the sight glass. The bike normally consumes only about 4-5 ounces over 5 thousand miles, from my experience (two oil changes). I did check the oil drain screw and that was completely dry so I do not believe that the oil leaked out of there.
I am wondering if anyone else has had a sudden consumption of oil with a cold spell. My current plan is to pick up some Marvel Mystery oil to mix in and refill the oil to the top of the sight glass.
Thank you for any advice you can give.
