1st thing to do on the cam chain tensioner is to make sure the lock screw on the left side is not tight. Loosen the nut and see if you can screw it in 1/2 turn or so. Back it off and tighten the nut again

Many people think the screw needs to be tight

You may have to "rebuild" the tensioner, as the seal is now over 30 years old. Naturally, there's a tutorial on the Basscliff site on how to do it right

Good for you on the bolt, some patience and luck go a long way with these old bikes. Sounds like you know your way around wrench.

When you check the tensioner setscrew and back it out, be careful. Only back it out 1/4 to 1/2 turn, NO MORE.

If you back it out more than 3/4 turn, the end of the screw is out of the notch in the tensioner rod that will keep it in the proper range.
