Techies, We've discussed this a little over 100,000 miles ago. Ive got a 99' standard with 159,000 miles on it and think its time to adjust the valves. The question is that it seems that the timing marker wheel that has marks to show TDC for the cylinders seem to be off. The last time i did this i pulled #1 plug and made sure of TDC. I'll do that again this time. But why aren't the marks correct?
Thanks again for all the awesome tech.

Are your valves chattering?

If not, leave it alone.

MGM has 243+K and the valves have only been adjusted twice.      Once at 2,000 miles cause it was hissing in the exhaust on one side..      Found a valve too tight.

2nd time one of our new techies wanted to adjust them.     He went through them 3 times and didn't change any valves settings.

That was at 212K on it.

So if it ain't broke don't muck with it.

Align the 1/2 mark to the arrow, then (with both valve covers off) wiggle the tappets.  Either #1 or  #2 should be tight and the other loose or vise verse.  If one of them is loose, the marks are right.

If the timing marks turn out to be really off, then its seems that that the timing belts probably have installed incorrectly.
As long as any cylinder is coming up on compression the followers will/should be on the flat of the cam and those valves can be checked for adjustment. Actually any time a follower/lifter is on the flat it can be adjusted.

the timing is controlled by the timing wheel, not the timing marker wheel. two different things. And, the timing marker wheel on my bike can be off because the previous owner installed a timing wheel and when he put the marker wheel on he ground the alignment spud on the back.
I remembered all that when i went to adjust my valves. Which didn't need it.
You guys are right again.  cooldude

Not to be smart butt here, but have you tried purchasing a replacement wheel?

Why would I? It's just a visual aid for checking valve clearances. When I changed the belts at 100,000 miles, i tightened it on location. Worse case is that a guy pulls #1 plug and make sure you're  at TDC. Mark the wheel and go 120' from there until you get them all checked and reset. cooldude

Common for the spud to get wiped.  You can tap the spud hole and install / locktight a small allen set screw. Use a fine thread.

OK, now I have no idea what you guys are talking about. I don't know what a timing wheel or timing marker wheel is. But, thats OK.
