stick your nose in the filler hole, you'll smell whether it's burned or not. Another consideration. I have had three bikes in the last year that were low on compression on one or more cylinders. One was 30 psi on one cyl of a twin, another was less than that on an inline 4 (Yamaha XJ650). Two of those bikes the compression came back after running the bikes for a while. The problem I suspect was rust on the valves or v seats and it was burned off.
