Kudos to you young sir ............................. life was a lot easier for me as an 18 year old - plenty of cheap parts [ Triumph, BSA, Enfield, etc.,etc.  ;D] and I missed military conscription [ which had just ended ] - by the way keep your head down.

I've sent parts to various peeps in Israel in the past few years - if there's anything I can look out for you just let me know. I'll be happy to search for parts, consolidate here and send them to you.

Thank you very much!! I'd really appreciate that!

I've got a bit of a problem with the motor hanger. They're all rusted and I want to soak them in vinegar but they still have the rubber bushings inside of them. I started prying them out but stopped to do a little research and found out that they're impossible to obtain. So I'm basically asking what should I do?
Here's a couple of pics of what the hangers currently look:



These are the parts I'm talking about:

Can you have them bead blasted? Vinegar will degrade the rubber. Another option would be to wire wheel them.

just paint them if you must and move on but there is nothing wrong with them and they are not even visible
its best not to start fixing things that do not need repair

Cool!  Any progress?

Yeah I ended up using a wire wheel on them and turned out pretty well. I'll post a pic of them later today.

Ok so I thought I was insane sanding pieces of aluminum over a bucket in the living room but after seeing the final results I'm blown away and it justifies the hours I've put on them. I still have a lot of sanding left but it's good to see what you'll achieve eventually to get you going.

Nice work on the polishing. I'm currently polishing a few bits for my 350, takes a time and effort but result is worth it.

Reassembly!!!
So I started reassembling the engine. I put the new pistons (65.5 mm) and made it up to the cylinder head. That's when I discovered that the right screw hole's threading is worn out.



(You can't actually see in in the picture but just to point out what hole I'm talking about)

So I have no clue on what to do now...

Also I noticed that there is a gap between the cylinders and top crankcase.



Is that gap gonna disappear when I tighten the 8 nuts on top of the cam case cover? Or should that not be there?

Here a pic of how the engine currently sits.



Also some pics of the process putting it back together (my friend photobombed a couple of them):

Looks like you have a dowel contacting the gasket. (you can see it's 'curled' slightly on left side) Lift cylinders slightly (about 1/4"- 6mm~8mm) and make fure gasket can sit flat against cylinder base. Then you should be able to lower everything without a gap

Ok so I found out what the problem was with the gap. The old o-rings were so dry that I didn't even notice them on the cylinders and I put the new ones on the old ones. So tomorrow I'll put it all back together.

Now, I just have to figure out what to do with the one screw hole that's threads are all screwed up...

Either get  it Helicoiled or buy a 'Recoil' kit. (may have to use eBay?)
They are the same as Helicoils but less than 1/3 the price.
I prefer 'Helicoil'/Recoil to the solid inserts, (solid are easier to fit but also cover a lot of bad work.)
 Just took a look on eBay, WOW, Helicoils have come way down in price.
 The sets I bought in the early 80's were almost $200 each

That's because back in the day, they didn't have the need for them.  Things were built better.

Sh1t, stuff rolling off the assembly line nowadays have coils in them already, and all they say is, oh well, we'll fix it if it hits the  warranty list.
