Had the shop put new cam chain tensioner, check valves, do coolant flush, brake flush. The shop said the valves are in does but at the top of spec. They said it meets Honda spec but just made it. Is this ok?! And how long should I wait to have them checked again since they are close?

 

What does "top of spec" mean? On the loose side of spec maybe? If they are on the loose side of spec, leave them alone until your next valve adjustment interval, or if the get really loud. It's better to be a little ticky on the loose side, than be too tight and burn a valve.
