I broke off one of those lugs on a 1970 k1 that I bought new.  The bike was probably 6 months old at the time.  A fellow welded it back on and did such a good job we didn't even have to chase the threads.  It can be fixed, fixed easily, and you can be on your way.  Oh, on mine the engine never came out of the bike.  Trust me, if they could fix it easily 40 years ago they can fix it easily today; inexpensively too.

Interesting...thanks for the encouragement. I need to find myself a good welding friend and see what I can do  :-\

Well, I'm sure of two things - first that mine was one of the very earliest ones to be broken and fixed; and second, that it sure wasn't the last.

While the guy who welded it is long dead now (he died of the flu, of all things, at the age of 27) he was a pretty good welder, but Miami (where the bike was) was full of such people then, as now.  I was not there when he fixed it, but it was obviouos he just chamfered the broken part and welded it back in.  The bike it was in was destroyed about three years later when a hit and run driver ran over the guy I sold it to but by that time it had over 25,000 miles on the repair and it held - meaning there was no metal fatigue resulting from the localized heat sufficient to result in a later crack due to vibration.  I really don't recall how much he charged me, but it was such a small amount that it wasn't memorable.  I have also had cases welded on outboard engines, but never with much success on them.

I've been thinking about this a little more...and I have a question that I'm hoping someone will easily be able to answer. Are there any real differences from a '77 750K to the '74 750K engines? Would they be a direct swap? If not, what is different?

There was a complete, non-running '77 750K that I nearly bought two weeks ago for $200....however, I just couldn't justify buying it because I didn't have the room.....I know the bike still hasn't been sold, so I might be able to pick it up for less than that now....plus, it would give me yet ANOTHER project bike to add to my collection of SOHC's...(I've become a bit of a hoarder...who knew this was such an obsession?)...

Thanks for all your help guys!

77 has a longer countershaft, can be run with the right rear carrier.  the gearing to sprocket shaft is different tooth count. Some 77/78 sprocket shafts have had premature wear.. Pipe mounts (on head) are studs, but can be changed.

 I think you can safely weld yours, if you are not worried about exact year from 73-76, I should have a case for you (got your email)

Definitely not worried about the year. Thanks Frank!
