Valve adjustment is by screw and locknut - easy peasy.

The bike was completely restored and painted at some point. I actually work with a guy who claims to have contributed to that effort. Since that time, it has seen some neglect.
Yeah, that's the thing with older bikes, sometimes their history is not entirely known. On the other hand, they're relatively easy to work on. OEM parts will be hard to come by although I think Suzuki has some sort of 'Classic bike parts' program where they do new production runs of older parts.
These oil burner GSXR's are fairly bulletproof though and aftermarket support is strong. Plus there's good parts interchangeability between the various models.

Crankcase breather? Yeah, just a gaping hole.
I love the smell of crankcase fumes in the morning!

The bike seems to run just fine on the VR1. The clutch and shifting are noticeably smoother, though that's normal for an oil change. My girlfriend just got her endorsement and we are practicing and wrenching every spare minute, so it doesn't look like I'll be having any high-rpm fun in the short term.
VR1's really a great oil with a healthy dose of antiwear additives, there's a reason why the classic car guys love the stuff. And it doesn't break the bank. Valvoline does not recommend its use with wet clutches, but after 2500 miles my clutch is fine and the transmission still shifts effortlessly.
Sounds like you've got a handle on the bike's issues, post some pics if you can.
Saw a beautiful '86 Limited Edition 750 the other day, brought a tear to my eye (I had an '86 non-LE and a '92).
