Honestly adjusting the valves would not be that bad if you found one out. And this 600 mile adjustment is just on the 13s the 14s no longer require, it so I heard. I have to say tappets would have been so much easer but just. This bike does not have cups over the shiims so you pull the plug out of the side of the head slide the rod out lift the rocker and replace the shim. It would take 5 more minutes to adjust them then to just check them. And once you have been there once the whold jub could be done in 3ish hours.
