Only just seen this thread, loving it!
Here's mine, owned for about 15 years, easily the most usable of my classic bikes, and not that far off my newer Guzz, at least in terms of comfort and distance ability!
I JUST finished my rebuild DAY AFTER the lockdown

, pretty much the same route you're going. Frame was pretty tatty with brake fluid and battery acid damage so thought, what the hell, do it properly (cue "scope creep").
Brakes and electrics ( a lot more to these than the slash 6 I did last year) were easily the most time consuming, especially making up all the metal brake pipes then finding I had the wrong nuts AFTER flaring the pipes
Went through the original loom, and after soda blasting every connector including the fuse box, found very little corrosion. Apart from the Valeo starter, everything including lego switchgear is original and all works fine. OK, it's only done 20-odd thousand miles, but there's a LOT of bollocks talked about 70's Guzzi electrics imho.
I had the gearbox (was getting a bit clunkier) and rear bevel (oil leak I couldn't fix with the "easy outer seal") sorted by Nigel at NBS and vapour blasted at the same time, I settled for soda blasting the crankcases myself, as I went through the engine a few years back.
Only other tricky job was bleeding up the brakes from empty after a full caliper rebuild, even with reverse bleeding and a syringe it took a while. I put a few extra bleed valves at the splitters etc.
I sourced a tatty Spada a few years back that had been nicely hot rodded, so swapped the good bits out of that into mine (Gilardoni 950 barrels, Le Mans heads, 36mm dell ortos, deep sump, P3 cam), so it goes quite nicely, hardly any faster, given the aerodynamics make a barn door look like the space shuttle, but good for overtakes etc.
Thing is, it's never handled that well, which I put down to the screen/weight etc. But on stripping down the forks I found it had suffered a tip over with steering lock on (I presume) and the fork stem was mullered! I'm now hoping for better things
Only jobs left are fit one horn, paint the (useless) panniers and fit a Sachse ignition when it arrives. I Went back to points after frying a DYNA but seems impossible to get decent quality points anymore, one is already playing up after a few thousand miles, wtf?
Keep posting, we all need vicarious biking projects right now
