These center pulleys have some surface rust. The tensioners should work but the bearings are due for replacement. I'll run it like this for now and refurbish those parts off the donor later.

Some of the valve adjusters look pitted. Using the smooth ones. a little out of focus but you get the idea.

brand NEW tappet adjuster screws and nuts are still available from Honda's parts system. ;)

SCREW, TAPPET ADJUSTING
90012-426-000

NUT, TAPPET ADJUSTING
90206-250-000

After rereading this entire thread and seeing visual proof of your belief that the valve train had been poorly maintained, I must offer up this Proactive advice.
Take a really good look at the tappet adjusting nut threads. If they have been previously overtightened (improperly torqued), the deformed threads in the tappet nut may not properly secure the tappet adjusting screw into the rocker arm anytime going forward, and you may unexpectedly be searching for a lost tappet adjusting nut and , worse case scenario, tappet adjusting screw in the base of the engine. :cry:

The tappet adjusting screw threads are more robust than a tappet adjusting nut's threads, and most likely won't show visible witness of "stretching."

per the Honda GL1000 Service Manual, page 3-10, set "lock nut torque" at 104-139 inch/ pound

just sayin'

I don't see how to check the torque on these but okay. I'll have to go by feel.

Also, should anything go on these threads? Anti-seize? Loctite? a little grease?

robbie202, good on you for procuring the new valve lash adjuster parts! tumb2
You will require an inch/pound torque wrench to accurately set the adjuster screw 'lock' nuts' torque specification . No need to apply anything to the adjuster screw and nut. Clean threads and drop of oil on the threads is adequate.
anyways..

Here's a link to the Honda GL1000 Shop Manual. Pages 33 and 34 will give you all the information you need for Valve Lash Clearance Adjustments.

Now........ about valve lash clearance adjustment procedures. Respectfully speaking to you, I kinda sense valve lash clearance adjustment isn't one of your normally practiced skills. Perhaps I'm incorrect.
anyways..
no you'd be correct if you sensed that lol.

10 foot pounds is 120 inch pounds so i have a torque wrench that is within spec on the lowest setting. however it is the socket type and it would cover up the slot in the adjuster.

it looks to me like i would need an open-end torque wrench or crow-foot tips to get an accurate torque on the lock nut WHILE simultaneously holding the threaded adjuster in place with a screwdriver.

It looks as if we are about at the same stage in our builds. I didn't do a full frame restore, but I ran into the same neglect and abuse of heads by the former owner. Mine has had broken timing belts on each side, with hammered valves. Just curious if the machine shop lapped in new valves or refurbished the old. I was told that the valve seats could be lapped, but not ground. BTW, your heads look clean enough to set on the coffee table without the rest of the family complaining too much.
Goldwings don't accelerate, they gain inertia.

1978 GL1000 - almost stock - needs a head replaced, parts are ready to install!
1979 GL1000 - Winter project/parts bike - custom "Busted"
1983 GL1100 Standard- raised from the dead and back to organ donor status :cry:
And the newest acquisition, 1979 XS 650F to be a sidecar tug. crossy.gif

Valve seats can be ground. The valves themselves cannot be ground as they have a stellite coating on them.

well technically this is not a "full frame restore" either since i left the engine block in the frame. everything else came off.
i don't really know what the machine shop did i just gave them all the old parts and new seals and it came back refurbished.
