Valve adjustments just aren't a big deal , fairly easy to do especially on these motors. But a warning to note, I know a few who were very insistent on keeping them snug and it ends in a short engine life. I don't suggest that you ignore them but I've owned a few 550 fours that I was less than diligent, the valves rattled and no problems. There is probably a YouTube video somewhere that shows how to do it. Usually took me a little over 3 hours, now I'll probably take 5 hours, but beer stops and bsing is part of the process.
