Loose valves?

Hey guys, I'm having an issue with my bike. Has not started in a week and I was worried about a slipped or broken cam chain. Long story short..... I removed and checked my automatic tensioner (ball type) and it's working fine. I took off the valve cover to make sure cam chain was in sync with crank (Lines up fine) and decided to check my valve adjustment. I last adjusted my valves back in the 80's at about 20,000 miles. I now have 61,000 on her. Yea I know....... but the great thing is that they are just about in spec!! See below....




EXH
#1 .006 in /.152 mm
#2 .009 in /.229 mm
#3 .009 in /.229 mm
#4 .007 in /.178 mm
INT
#1 .007 in /.178 mm
#2 .006 in /.152 mm
#3 .005 in /.127 mm
#4 .007 in /.178 mm

Not a single one was tight! Should I go thru all the work for the two exhaust (.009 in /.229 mm) and maybe the three at .007 in /.178 mm or would it be ok? 40,000 miles and hardly any valve seat wear. I would think they would be tight after that many miles.

my 10 cents,,, run it, I would figure you prob got another 10-20k on it before they start getting tight.

I intentionally run mine leaning towards the loose side. If yours are a shade loose, they are OK.

Excellant,Thanks guys. I was really surprised to see them at those specs after that many miles. Are these great motors or what? Thanks for your response! I'll button it up and run it.
