Burning Oil. Maybe?
So, I'm thinking my '89 is burning a bit of oil...
I recently changed the oi. Used the Rotella T 15w40 that I've seen recommended on here in quite a few places.
poured new oil directly into the filter to eliminate/reduce air bubbles in the system, but I didn't try doing the "burp" trick this time around (loosen the filter a bit with the engine running to let the last bit of air out) as when I did this last time, I obviously did something wrong and blew the gasket out of the oil filter.
Now... after riding around a bit, I noticed that the oil level in the sight glass had dropped about the thickness of 2 quarters from the top/max fill line. Assuming that this was just being pulled into a remaining air pocket in the filter, I topped the oil off and went for a ride. About 100 miles later, the oil leave had dropped back down approximately the same amount. I even rechecked the level after sitting several hours in case there was still oil dripping down from having been run.
Also, I never noticed the oil level dropping any prior do doing the last oil change.
I get no smoke from the exhaust, the bike starts up first try every time (if the choke is on of course) I get pretty decent power out of the bike. I'm getting a top speed of close to 100mph with an undersized tire.
I DO have some slight oil on the threads of the spark plugs, but the electrodes themselves are dry and look otherwise normal. I don't see any obvious oil leaks or seepage from anywhere. Nothing in the air filters to suggest over filling.
I currently have a piece of tape over half of the sight glass to mark the current oil level so I can watch to see if It falls more on the next ride I take so well see what happens there.
I suspect that I am just overreacting and the oil level will normalize shortly, but I wanted to get some opinions from those who know a bit more then myself.
......I'd rather wake up in the middle of nowhere then in any city on earth.
