I tore into checking and adjusting the valves on my '80 550L. What I found was that I couldn't fit even my thinnest feeler guage (.0015) in, except for #2, which I could get the .0020 in. Waaaaaay to tight right?
A little history- I picked up this bike after it had sat for a long time. It has 15,000 original miles. Don't know for sure when it ran last, but the last time it was registered was 1990, and the last registered owner died in 2001. I cleaned it up, serviced the carbs and electrical, and got it running. It never ran on the #3 cylinder, but I wanted to know the valve condition before I go chasing ghosts.
Long and short, for the mileage, they seem really tight. Can the valves just tighten up over time sitting there? Am I overlooking a basic maintenance issue that needs to be handled before I get an accurate reading?
Oh- compression was good before I tore into it last fall. Can't remember exactly, but all were close to where they should be
-thanks!
