Checked my oil before heading out on an 80 mile trip. It was just above the add mark when cold..I put a little in and took off. While on the trip, I noticed my Eitms activated a few times while sitting at lights..the ambient air was cooler than normal for Central Florida so I thought it was weird. Anyway, got home and checked the oil while bike was hot...she is 1/2 a quart low. I know with decreased volume in crank case the temps will go up. My question is..I have no obvious leaks on the bike and the A/C has no oil in it so where did the oil go? I am going to drain oil tomorrow and replace with M1 20W50.
