Hey guys
I have the Top-end off from the engine.
Is it possible to do a valve-adjustment when its removed from the engine?

...Absolutely. -
I've wondered about that myself. Rotating the cam shafts without the chain... How do you do that?Roger

It's not easy to do it off the engine.Ed
To measure is to know.

Okay I got it, I'll make a jig to hold the head on a sawhorse. Then take a sprocket and crank from a bicycle and mount underneath on an axle. Then I'll wrap the chain around and use the pedals to rotate the cams slowly. I will put a bicycle seat on the sawhorse for comfort.
On second thought, maybe I'll spend that time and just reassemble the engine!Roger

I'm kind of intrigued to see if it's possible now. Not the bicycle sprocket thing, I was just kidding around, but rotating the cams without damaging anything.
I bought a strap wrench which should work if there a spot to wrap it around the cam shafts. I'll try when I get home and see if it works.

When you get done fooling around, just be sure to have the cam lobes in the proper positions when measuring your clearances.
Might also be a good time to take advantage of the offer in my signature.

Well, the strap wrench was too wide to fit on the gs850 cam. If the wrench was 3/4" wide it may work, assuming it's strong enough!Roger

I found a strap that works. It wraps around the sprocket on the cam shaft and rotates it with ease. The strap is like a serpentine belt material, tough stuff. It barely fits in the cam chain tunnel which gets narrow towards the bottom of the head, but it does fit. There is a cam chain guide held on by two bolts that I had to remove from the intake side to get the strap through. Found it at Lowes near the water softeners, item #148976 if you want to search online. Surely the timing will need to be adjusted and there's lots of other worms in this can though! I was planning on tearing down this head anyway but really wanted to be able to get the clearances within specs before putting it all back together.
Rockstone, I hope this helps with your project.Roger
