800 Valves

Any one still checking their valve clearances over 40K miles, I would have thought everything would be seated by then where you no longer have to worry about that.

Valve seats continue to recede throughout engine life and must be checked according to manufacturers recommendation or your engine may suffer the consequences.

I know that I was wondering what others were seeing, last time I had my bike in the Shop it had 40,000 miles and they said my valves did not need to be checked.
The shop told me it was running fine, but last time I had them checked was at 30000 and they said I had one shim that was tight and they changed it out.
Now I have 42000 on my bike runs great so I would like to hear if others had to change out their shims much over 40000.

If you have now gone over 12K miles since last check, you need to check your valve clearances because you are overdue. Owner's Manual states: 7,500 miles, 15K, 24K. Most check them every 10K after that. Valve clearances must be checked; they do not 'wear in'. As sfair so eloquently stated, "Valve seats continue to recede throughout engine life". Just because you (or someone else) only changed 1 shim 10K miles ago, you may need to change the other 7 now! The ones that were not changed may have been just barely within spec at that time.

But to answer your original question, yes, I check my valve clearances over 40K. I do mine probably every 6-8K; I get bored and need the activity. LOL And there are always shims that need changing or are close. A bike can seem to be running fine, but if the valve clearances are not within spec, your bike will soon NOT be running fine and you are then looking at major work to repair.

I learned to do them myself a long time ago--saves tons of money and I know they are done right! You too can learn. There is an excellent sticky on it and many kind folks here to help you along the way.

Thanks, I am not sure why when I asked them to check my shims they said it did not need that, if they say it again I will go to another shop.
