I'm wary of drilling the frame and of the strength of a bolt without welding. Jarred, how strong was that fix and did you cut the head off and weld the shoulder to the frame?
Augi, I may be selling this bike. The seat going on and off has taken its toll on the stud threads and the exhaust is hanging from the right side. I'm just looking to see what it will take to make it right.
Davmo suggested adding some weld to the existing threads then grinding and re-threading. This actually sounds like the easiest way out without having to repaint large parts of the frame.

Bringing back an old thread, haha, to see if someone has a source for the studs for the Z50a K3-78? one of mine is stripped out and I tried chasing new 10x1.25 threads on it only to find there is not enough material to hold torque.
it is clear it’s a welded on stud, like a wheel stud built welded on. i have searched the web for weld studs and other items with no exact match.
appreciate the help.

I would just find a shoulder bolt that is a little longer than you need, trim the threaded end and overall length to match the original. The old bolt is removed by grinding the area where it is welded flush with the surrounding metal and then whacking the bolt with a hammer. When welding in the new bolt, extend it out the backside a couple millimeters and weld it in. If it is extended slightly, it allows someone else to grind it out a second time without having to drill it. That is how Honda does it. A competent welder should be able to do it in 20 minutes or less. The original bolts were unplated with black painted ends from the factory, if you care about that stuff.

That’s what I was thinking as well. I found a flange bolt that has about the right dimensions other than total length. But that’s easy to fix. I have a MiG welder and some experience but it may be better off being TIG welded. If that’s the case may need to pull the swing arm off and take it to a buddy to TIG.

As I examined the swing arm I also discovered the back side of the left side shock mount is ground off. This was as a result of the studs they had placed in the hub. Actually surprised it has not bent over, strong welds. So both sides are in need of repair. the left can just be fill welded and I got a metric bolt that I will cut to length and weld on. Funny thing is the bolt had the exact same specs, the unthreaded section of the bolt, as the studs.
