Been following this channel for a while. The owner Frank has delat with loads of Brit bikes, many Commandos (owns one as well).
This 750 FastBack came in with a never started since previously restored engine. See his earlier videos of many, many attempts to sort out why it wasn't starting. Low compression seems to be the only obvious problem. So now he's stripped it down and did find some stuch piston rings and missing head studs/stud nuts, likely accounting for low compression.
Anyway, he asks for advice on if the pistons are a suitable choice....appear to have the oil drain "slots" that I think I've heard were problematic and maybe cases of top crowns blowing off?
I can provide any sage advice gathered here back to Frank if you'd prefer not to make comments direct on his channel....
