How do you go about repairing that shock mount?

I have done some work on this, but off and on, with regular work schedule getting in the way, Sean stopping by on his Belfast 2 Belfast rideabout needed to work on his bike and my buying more used parts, cleaning them up and shuffling stuff around in the shop, worked on and fixed my K5 wiring problem and I haven't updated this thread in a while even though I did get a few things done on it, so here's the updates....

Made the decision to clean up this frame and paint it as a friend wants to buy it as a rider.

A few weeks ago I cut off the remaining threads of the shock mount, drilled a hole in multiple sizes up to the 8.8mm size listed for the 10mmx1.25 tap. The drilling went well until I got near the weld point of the mount to the frame, the welds hardened the steel, dulled up a few drill bits but got it to a good depth finally. I had to get another tap as the tap and did set had a bottom tap in that size and it wouldn't start tapping. Talking with a friend who told me to get a starting tap, they have a tapered end to start the threading. That made the difference, followed up with the bottom tap. Cleaned out the oil from the threads and put some Loctite blue on the threads and tightened the stud in place. All better.

I sent off the 2 gas tanks and 2 dented oil tanks to the PDR guy a month ago, he called a week ago and said he couldn't do the oil tanks as they are too heavy gauge steel and was getting going on the gas tanks. Hopefully hearing from him soon. So I will be looking for a K6 oil tank that isn't dented.... of course the K6 oil tank is a 1 year only because of the changes in the rear vents but maybe I can make an earlier tank work.
I bought another set of 086A carbs at a swapmeet in May that aren't monkey fisted, did an initial clean in the ultrasonic tank and still need to finish them up. I might use a friend's vaporhone on them if I get the time to do them up nicely.
This afternoon I will head over to my sister's house and stay with my mom while my sister goes camping up on the Maine coast next week so I won't get anything done on this after this morning for the next week. But I'll get some good time with mom.

Nice, clean repair. I like it!

Thanks John 😊

I like your shock stud repair    Did you use a hardened stud(10.9 or 12.9?)to replace it ?
Did you use hardened drills and taps ?
Where did you source your materials ?
Stu,would air pressure pop the dent out of that oil tank you have ?

Not sure that the stud is hardened? Bought at Ace $3.09
Cobalt drill bits after my old bits dulled up fast. Amazon $50/set. And had to order an 8.8mm drill bit from Amazon as there wasn't one locally.
Taps, have a set from HF, Bought a new Irwin 10mm starting tap at Ace

Added pictures that wouldn't load before in last post

[grcamna2]

I see.
I imagine you finished tapping out the depth of the hole using the bottoming tap;did the tap struggle going through the hardened steel toward the bottom near the weld ?

[newday777]

It was tight yes, lots of working back and forth.

[newday777]

And yes I did finish with the bottom tap.

Thanks, Stu! I always wondered if those bolsters were hollow or not, in case I'd have to do what you just did.
So far, I've been lucky not to...

Well I've been tardy here....again...over a year this time.
I got back onto #3 project K6 off and on this spring and summer.
Found an 086A carb body to replace the one with the busted and crude repair of the post. Put the carbs on and found they still must have some MBTE residue in the idle ports and need another go through... but the motor sounds good.
Put on a new starter cover and bolts.
Put in a new HondaMan ATC fuse panel.
Put a good rear fender and taillight on.
Got it registered and a title for it.
Put on a new Oring chain and sprockets.
Put on a rideable K6 tank(needs a repaint!), I bought the tank a year ago and did the electrolysis derust followed up with Evaporust and 2 stroke oil to preserve the inside.
Cleaned, flushed and bled the front brake.
Put on a set of rear turn signals on with some K8 rear turn stems and a K1/K2 grab bar(temporary until I get a good K6 grab handle).
Put on a K8 speedo until I get around to rebuild the original speedo that was damaged by the original owner.
Put on a Delkevic 4into1 system for the time being.
All the wiring checks out.
I still need to reclean the carbs so I can take it for a shake down ride and to bike night, the frame and motor need to get repainted(motor out and new gaskets).
I have a new points cover for it.

So it is coming along, albeit slowly, when I have time and don't get distracted by my other projects. I think they blame that on my attention deficit distractions.....

Looking good....lots of iron in the fire so to speak.

That tank deserves a repaint….. it’s spotless inside!
