I started this thread in the not-so-modern forum a long time ago based on a question I'd asked, but I'll do the full project recap here.

I bought this bike back in '97 as a package deal with a super rusty but gorgeous '63 VNB roundtail. I brought both of them back to life then with a lot of modifications, but on a college student's budget, so some corners were cut. I gave this VBB to my dad back in 2000 and it's been sitting in a garage since then getting occasional attention. A few years ago we decided to bring it back to life the right way.

We've been lucky to have a family friend's hangar to work in, camping next to some amazing cars. Today I finally got to open up all 4 gears up and down the airport taxiway and it felt great.

This is the bike's journey, including all the strange choices I made along the way.
Here's where I started back in the 90s

In the dank garage I was renting in college.  Seized motor out and the rest of the bike all dismantled. The VNB is just barely visible in the corner.

Skipping over some of the original paint job, but I had a connection to someone who painted hot rods and they shot a nice red/cream paint job for an amazingly low price.  Paint has never been my strong suit so I was happy to have someone else do it.

I made some... questionable wiring decisions back then, including a custom instrument panel in the legshield.  It worked great with a tach and fuel gauge, but was ridiculous in hindsight.

Here's what it looked like when I first got it put together.  The original 150 motor was within the realm of salvage, but I had an opportunity to pick up a cheap p200 motor and a 10" GL fork instead, and I went that route.

Later I swapped the GL fork for a PK fork with a semi-hydraulic brake.  Here is the bike a few years ago after hibernating, safe in the hangar.

Lots of weird stuff going on here, including the remnants of vinyl lining behind the battery tray.  Weird college brain tried to line the whole glovebox with it.  Don't ask why, I took it out soon after I did it.

The PK fork was unceremoniously cut down to accommodate the VBB fender, but it was never quite right and rubbed against the body regardless of my hacks.

Weird college brain strikes again.  Cheap fog light I found fit nicely in the horn well, and so why not mount the horn under the fender?

The 90s were wild, man.  At least for me I guess.  Silicone goop instead of a real gasket for the glovebox door.

I couldn't find a decent turn signal switch back then, so this is a cheap substitute I was able to source, crudely screwed into the handlebar.

I wound up replacing the ignition and upgrading to a lighter flywheel.  The minute I started monkeying around in the junction box, the original wires just disintegrated.

Motor out, and it's still in good shape.  It'll have to be rebuilt sometime in the not-so-distant future, but that's a future problem.  At least now it has a new cosa clutch and upgraded ignition.

Trying a different fender.  This time an aftermarket Rally mudguard, but it's not what I wound up using in the end.  Still trying to figure that out in this photo, working on making the mounting work without rubbing against the body.

Realizing at this point that the side mounting would be still problematic without further surgery on the fork.

Realizing I wanted to go fully hydraulic and not use the semi-hydraulic kit that was already a little corroded.  I tried a couple options but this kit from Scooter Center was the right choice.

Fixing the issue I had before with missing steering stops.  This was my first attempt at getting things lined up correctly before officially fixing blocks to the column.

Shiny new tank.  The original one had been hacked up with a generic fuel gauge sender and my welding skills were no match for thin, abused steel.

You can see the mudguard I decided to go with.  GS style made for 10" forks, so no questionable modifications needed.  I couldn't be happier with that choice.

I had originally mounted a SIP center rack instead of the center floor mat.  Seemed like a cool idea at the time, but I decided to weld up those holes and go a little more traditional there.

My first attempt to drill a hole for the hydraulic brake line was poorly placed, so I removed the paint off that side of the headset to fill the hole and do it right.

Fast forward to a full repaint.  This was an adventure and a half, resulting in the painter completely ghosting us despite doing the fender wrong.  We'll fix that in some upcoming shots.

The lack of mudguard here shows we're working on something.  Basically, the painter took some liberties in making everything 2-tone except for a fully white mudguard that just didn't look right.  Dry fitting without it for now.

Time to fix the mudguard paint in a cheap paint tent.  Had to find a place that would mix up a near-perfect match since the original painter fell off the face of the earth and never gave me the codes or any touch-up paint.

Sanded back all the clear coat and cleaned the mudguard well before masking off to add the green it was sorely lacking.

Green went on nicely with several coats, and now onto the metalflake clearcoat.

it turned out great.  Kind of wish I'd left a pinstripe masked into it, but I'm happy nonetheless.

My dad was a good sport about my plans changing on the wiring and cable runs despite spending hours with a soldering iron and wire strippers.  Pretty sure 50% of our time was spent on headset wiring alone

I plugged up the unholy mess I had originally put in the aluminum handlebar for the turn signal switch, and that made my life more difficult by needing to figure out a better solution for indicator buttons on the right side...  Stay tuned.

This may have been the 5th, 10th, or 25th time we rewired the headset.  We only took it off a few times, including re-running full cables once

Continued. Here's where necessity becomes the mother of invention for the handlebar switches.
Short of completely rewiring the original switch assembly (of which I tried 2 prototypes), I opted for creating my own. Here's my first attempt at a 3d printed housing for my switch set up.

Prototype 2 is looking a little better but still rough.  I'll have push buttons for high beam, left/right turn, horn, and kill.  The high/left/right will be lighted so I have visual indication of what's on.

This is what I went with.  Some UV cure resin, sanding, and aluminum paint smooth out the finished look a lot.  and yes, the wiring has been simplified inside the unit on the final assembly.

The seat has a magnetic latch, which I'm loving over some janky manual latch mechanism that doesn't like to line up and may or may not take a special sized latching stem.

This is the point at which I realize the original clutch is seized and I had a choice of either rebuilding or upgrading.  Cosa clutch order it is.  Add another day of frustration when I realize the cosa clutch has a different nut than stock p200...

First test ride was solid except for the lack of rear brake which was a simple brake shoe cleaning and cable tightening.

Officially running!  Kickstart is finicky, so I'll add that to the pro column of why I need to do a motor rebuild.  All four gears are pretty solid pulls and I'm loving the SIP road pipe over the Sito plus I had on here before.

Here are those plans I had for the legshield glovebox.  Choke pull on the left and p200e ignition switch on the right.  The internals of the glovebox also hold the flasher and control box for the SIP speedometer.

Fin! The project is pretty much complete. Well, for now. I mean, it's a vintage Vespa after all...
