Since Honda claims a valve adjustment at 20 hours and then at 100 hours, how often should they be adjusted.

Has anyone never had their valves adjusted and did you have trouble? Just a question to throw out for my information.

 

What honda claimed sounds correct. I had mine adjusted after 10 hrs (what the bomb. service manual states). I would adjust your valves once a year or your power may decrease and can make the machine start harder with tight valves.

If there isnt a place online to help you with adjusting them get a service manual. Just take your time and you shouldnt have a problem.

 

Honda recommends inspecting the valve clearence every 600 miles or 100 hours.
