1969 R60/2 not running
The plugs have a spark when grounded to the fins, I’m not thinking the carbs because up till then it was running and idling fine. And what are the chances of both carbs failing at the same time.
One thing I did notice is when I was riding just before having the problem is that the idle would stay high for a couple of seconds then stabilize.
Now when I attempt to start it, the bike starts and Boggs down and stalls right away.
Any suggestions would be appreciated.

I've never experienced it and

I was under the impression that the piston can seize but then after a bit of time, the bike will run again, until the next seizure. I suspect there's some damage being done with each seizure.
That's about all I could think of initially when you said that you were running along fine and then the engine just bogged down.
Check the simple stuff. Make sure that the air filter hasn't collapsed or is blocked.

My first thought was a
59-69
I'm also thinking crap/debris
And your description sounds all to familiar.
Have you flushed or ever flushed your tank and fuel lines?
Are you running filters to each carb?
Have you personally cleaned and tuned your carbs?
You only need the smallest bit of crap the size of several of your hairs to bog things up.
Lets hope it's something like this and not a seized motor. If you can turn the motor with your foot that is a good sign.

Not to belabor the obvious,
You might also consider the condensor, as they will allow a quick start and then stop!

All good suggestions - and I
If you decide you may have contaminated gas you will need to remove the carbs and clean them. No big deal but record your adjustment screws settings so you can get close when you put them back together before you re-balance them. Do them separately so you don't mix up parts between them. Sometimes just some carb/choke cleaner and compressed air in the right places will get the job done.
And also if you suspect contaminated gas, flush the tank and replace your fuel lines and filter(s), of course.
Good luck!
