Researching this subject revealed some conversation here about the valve adjustment gap getting closer overtime. I just wrapped my carb rebuild project and decided to check the valves as it has been 16,000 miles since they were last done. On all but two I could not slip the appropriate feeler gauge in. I did follow the shop manual sequence and there was side to side movement in the rocker arm before I made adjustments. So I have to agree after finding this out for myself. Is the change coming from wear in the valve seat or the valve face?

Answer to your question is , yes. As long as you check the clearance while the rocker is on the flat of the cam you're good. Its the valve that you can't hear that'll bite ya. These monsters are not noted for the valve lash moving around alot, they tend to stay put, so checking when you did is good and it shouldn't have to be looked at for quite some time.

If that many were out.......it wasnt wear, it was the way they were adjusted last time. These things dont change that much. And I have never seen that many get out of adjustment between settings. They were simply adjusted wrong |

The responses above are right on. I check clearances annually while my Valk is in my basement workshop over the winter. I have never adjusted more than 2 or 3 valves. This year it was only the #1 intake.
I would think you would have noticed performance or other issues once the engine warms up. I would think your valves would be hanging open.

Some of my have been crossed out [ I can't think of another or the correct term] lately, not sure why. I'm sure I'm probably the cause but don't know why.

I adjusted, (checked) my valves at 23K, they were A OK. Checked them again at 50K in a Motel parking lot on the way to Alaska. Still on the button.
I have not checked them since and MGM has 242,724 miles on him. Even Triked out he still runs like a scolded dog. Even pissed off a HD rider today. He pulled up beside me, looked over and said ya got a nice lookin anchor there. Light turned green and we cracked them at the same time, I jumped again and kept crawling out in front, I never saw him again, he turned off at the next exit.
To bad a buddy of his couldn't of seen his ass whompin.

They were simply adjusted wrong Chris, I did the adjustments the last time. The bike had been running just fine so I don't think any of the valves were open all the time. One thing I did not do was to try thinner feeler gauges to see just how much of a change there was. |

All Im saying is the chance that many all changed that much is way small compared to the chance you did somethig a wee bit different last time compared to this time |

The only time my valves actually "needed" adjustment was after I personlly adjusted them! The local dealership quoted me four hours @$90.00 per hr. I thought it was going to be alot simpler than it was. I used standard feeler gauges and did'nt take my time and be very careful. It still only took me 2.5 hours. The second time, I used "go-no-go" gauges, got them all right on the money and I used the "read-do-read-double check" system, setting on a stool in the garage and still only took a little over two hours! Out of the four or five adjustments, none were found to "out" by more than 1/1000, so now I go about 40 to 50K between checks and this is on an engine with 264K. So, if you keep a good quality oil in there and are not constantly "red-lining", then just let'um be for about 50K or so between checks and keep on riding.

In 2006 when I got this bike it only had 850 miles on it and not running. The PO left it sit for about three years before deciding to sell it. Working on it myself revealed three cylinders with low compression. The PO had built carbon on the valves??????????? I reseated every valve by hand just enough to remove the carbon and had set the gaps on a brand new engine so this is the first run-in check.
Thanks for all the responses.
