You say you are adjusting the clutch instead of the primary chain? it is a bit hard to confuse the two.
So now you have to tell me what you did adjusting the clutch, so that I can tell you what you have to do to make it right again.
As for adjusting the primary chain..... the primary cover must be removed on a 1971. Also, you want to have a brand new primary cover gasket in hand before you remove the cover.
If you do not have a gasket..... get one. Your manual should be there by the time the gasket arrives.
I can give instruction on adjusting the chain if you need it now........ pg

yea it was kind of a dumb thing to do,what I did was loosen locking nut and turn in clockwise but not being sure I counted number of turns.when I saw that was not tightening primary chain I stoped and turned back same number of turns and tightened down locking nut,do you think that was ok? I checked tention on clutch lever it was same as before a little stiff but no clicks or pops.thanks for going to the trouble to post the pics and specs.

Yep, you were adjusting the clutch all right! Actually, you were adjusting the clutch release ramp.
It is difficult to determine if you have it back like you found it, so here is how you do the proper adjustment:
(1) Loosen the lock nut (12) on the cable adjuster sleeve (14) where it goes into the primary cover.
Screw the coil adjuster sleeve (item 14) inward until there is a large amount of slack in the cable at the clutch lever.
(2) Remove the center plug (1).
Loosen the lock nut (2) and turn in the screw (4) until you feel resistance.
Turn the screw inward another 2 full turns.
(3) Now go back to the coil adjusting sleeve (14) and turn it outward until there is no slack in the cable at the clutch lever. You want no slack nor do you want any load on the cable. Just a neutral position where the cable has neither slack nor load.
(4) Tighten down the lock nut (12) on the adjuster sleeve. You are done with this item. This is the correct cable adjustment.
(5) Now, go back to the center adjusting screw (4).
Turn it out slowly until it gets easier to turn. Stop.
Turn it slowly back in until it gets resistance. Stop.
Now, back the screw out 1/4 to 1/2 turn (max) to establish the correct end play. Making sure the screw does not turn, lock down the nut (1) tightly.
You have now adjusted the clutch cable and clutch release correctly.
Here is another pic to see the different parts........

support brace bolt
thanks big for the clutch adjustment,great step by step.I removed primary cover this morning and all looks good on inspection,gear teeth and chain look like new also chain shoe is in like new shape but missing is support brace bolt#6 I have looked all over inside of primary no bolt ,nut ,washer could this have been left off on last adjustment just dont know? but Iam sure it is not a good thing!! I can tell that shoe backet is slightly bent downward but just very little .this leads me to think it was not replaced last time Ithought I would take off shoe and bracket inspect and see if I could straighten it reassemble and replace missing bolt.any thoughts?? I got lucky on primary gasket local shop had one.THANKS AGAIN....

Oh Yeah, missing bolt #6 is going to make it impossible to hold the shoe in place.
Get bolt #6 for sure. Also, this bolt (original) has a flanged washer head on it. The original did not use a washer.
If you cannot get that type, then use a flat washer for sure.
This bolt strips easily, so look at the condition of the threads now. The threads on the bracket, I'm referring to.
If you cannot find the bolt, then it was most certainly left out by a careless mechanic upon reassembly............. pg

#6 bolt and threads
I found another with flange in my 10,000 bolt collection,same size and thread,length, must have the luck today. As for the threads on flange look ok just not very heafty just like you said. I put a drip lock tight on them I know I my regret it later but I just dont trust it.Iam sure if it came off it could do some damage.
