Alright, finally some time for a proper update post. Pictures are clickable for full-size
TL;DR: At this point it's fair to say that my airbox boots #2 and #3 are shot.
I have put on new clamps, but the issue did persist.
Here's a shot of #4 carb after buttoning up. I forgot to take a picture of the other ones, unfortunately.
As one can see, the clamps are screw-style stainless steel ones, and they're a bit wider than stock. By using a hex screw, they allow for serious tension. So I tightened them up really good. Still, no dice
For fear of completely breaking either the carb inlet/outlet this way or the the boots, I didn't tighten as much as my hands would allow. Didn't want to leave the bike in the workshop for numerous weeks until replacement parts arrive, and the current state of affairs allows for short jaunts in my region. And my current gear won't allow me to ride in these conditions (-2?C / 29?F) for more than twenty minutes anyway.
Here's a vid of the issue for the interested reader, highlighting what I tried to put into text earlier on:
Unfortunately, I forgot to take a video how the RPM's change when spraying starter fluid on the airbox boots #2 / #3.
Also, when I was referring to the "throttle shaft seal", I meant this:
(It probably has a different name. But the parts schematics are just that tiny bit too far away right now
).
Just for posterity some additional pictures of the process:
Jury-rigged external fuel tank:
New clamps on the intake boots before putting the carbs back on (picture taken a few days ago, and not at the same place)
Now on to order replacement parts.
