You would think they coulda designed them to be easier to adjust ! i mean, having to remove the cams to add shims is just nuts. I remember on my old hondas you'd just pop a cap off, turn the crank till the lobe was in the correct postion, then open a nut that locks the tappet in place and adjust it with a screwdriver then relock the nut and replace the cap. Each valve was a 3-5 min job. The triumph is a lot more trouble just to check clearnaces, but go forbid you actually have to adjust them ! Crazy....
