70,000 mile valve lash

Having neglected to check the valve clearance since the bike was new, I've been fearing the day when a burnt valve appears with only myself to blame. As the bike has been ridden for 10 years and 70k miles it should be interesting to note the results.

Here are the numbers grouped 1-4

Exhaust:

9 9 9 9 9 9 8 8

Intake:

8 7 7 8 77 77

It was quite surprising, as only #4 showed any change from spec on the exhaust side.

The other surprise was to see all the intakes getting loose, not sure why as no sign of wear was seen on the lobes or followers.

Decided to reshim the intakes, and leave the exhaust alone.

I'll probably check it again later this year as I forgot to remeasure before reassembling!

Checked mine @ 30k, was 100% in spec. Will wait another 30k before checking again.

PErhaps we're not riding these bikes hard enough...

Mine finally needed a little adjustment at 100k miles. Gotta love riding a Honda...
