You could do it for the peace of mind and it's likely that if its running fine there will be no adjustment. My 07 has 71k miles and I'm going to check them myself and expecting the valves to be good. Again for the peice of mind. But I'm interested in what others say too.

For peace of mind it is a good idea to have the clearances checked.
I had done it twice on the 2003 I sold last December and no adjustment was necessary at 58,668 and 97,375 miles.
I recently sold that bike with 117,000 miles on it.

On my friends 2003 with 67,684 miles, I had to adjust the clearance on 8 of the 12 valves. To my knowledge the clearances had never been checked. They were not out much, but they were out of tolerance on the tight side. Tolerance is Exhaust .009" +/- .001" Intake .006" +/- .001". None were loose, just tight.

The thing is, the valve train does not make noise when it needs adjusting. Valve seat, valve stem, cam and shim wear makes the train tight instead of loose.

It is expensive because there is a bit of labor involved to do the tear down and inspection and a bit more to do an adjustment if necessary. The engine needs to be stone cold so it has to be left at the shop so it is cold when the process is started.

It would be a good idea to get it done. I did mine at 32K. I did them myself. All the valves were within spec, but a few were close to being out. I now have a baseline to see what they look like at 64K.

Most that have it done say no adjustments were required. It is a good idea to have it checked at least once. If you want to save a little have the dealer check the valves and do the oil and air filter change yourself.

If you want a snappier throttle, quicker starts, smoother running, and possibly better mpg, it needs done every 32k.

I checked mine last week and they are all in tolerance with 71k miles. Now I have a baseline also. I'll check again in 2 years and see if it has changed. That will be another 30k miles later. It was not a hard job at all. I did replace the valve cover gaskets too.

I would suggest that you wait until the Honda recommended service mileage to have them checked as I have found that certain dealers use this ploy to get extra dollars for work not done, I have a friend that asked how often I checked my valves and I told him every 32,000 like Honda recommended he said the local dealer suggested that it be done every 2 years even though the bike might only get 3 to 5 thousand miles a yeat . So the next time it went in we marked the valve covers and chain covers, took pictures and sent it to the dealer. Guess what buddy got a call bike was done, valves checked and all was good. Went to pick up bike and asked dealer to follow us to bike the valve covers were never off therefore the valves were not checked, buddy got the service for free and never went back. If your bike was checked at 32,000 then wait till 64,000 did mine twice and no adjustment was needed.
