I'm doing a valve adjustment on a 2011 CBR250R. I've got the lash and current shims measured.
Both exhaust valves and one intake valve were tight. I thought it would be best to order shims that would put my valve lash slightly under the upper end of the spec (IN: 0.19mm, EX 0.30mm), Since the valve lash tends to get tighter over time instead of looser.
After ordering new shims both exhaust valves should be around 0.28mm and intake around 0.18mm. I could order the next thicker shims (+0.025mm) and be closer to the center of the spec (IN: 0.16, EX: 0.26).
Any reason to choose one over the other?
