Modern Vespa

I'm loving the Sun Yellow, myself. And you can put a hell of a big LED headlight in that Euro headset, too, if that's your thing.

Rallies were produced in about 20 different colors over the years in different markets ... here's a list:

... and I agree, China Blue is spectacular. Maybe we can get MJ to post a glamor shot of his Azzuro Cina beauty.

I think the headsets were designed to accommodate the bar end lights.

This is my throttle tube. It has a plastic sleeve with a thread pattern inside. I wondered what that was for, but must be those.

They were used for some import markets that required turn signals. But the US must have required front and rear.

I'd imagine they get broken a lot. They're in such a precarious place.

Probably something else. Bar end indicators used "secondary" tubes inside. Here's how the set looks...

aah! It's great you can get the whole set!

Now I'm considering changing the headset, but conflicted, bc it's a complete American spec one, and there are so few of those left.

I decided on a color. Rosso Corallo 880.

It's a red with a bit of pink and brown in it. Very 1970s. Even though it wasn't a 1974 color.

Now have to figure out how to find the paint code.

The code is 880. Depending the paint company it will be PIA 880, PIAG 880...

Maybe it's not that hard?

It looks like Max Meyer is owned by an American company called PPG, that even has a store in San Francisco.

Can I just give them the code?

PPG did not transfer that color code over to their newer line.
You can use that color code at a Glasurit Paint store and they can mix it for you.

Would I need to order and ship from Europe?

Google the closet Glasurit Paint store near you. Give them a call to see if they can mix that paint code. They can mix the old Max Meyer paint codes.

It looks like Glasurit is the owned by BASF. They have some distributors locally. I'll try calling.

Replacements for broken parts.

Managed to find a 1974 Rally case. Still going to try to repair the broken one, but in case it's not possible.

Were the flywheel fans on Rallys painted, or bare aluminum?

This is something I've never seen.

The handlebar had some kind of impact at some point, pushing over the position of the aluminum part by quite a lot.

There's only a minor visible damage to the end of the bar. But must have been a pretty severe impact.

Should probably check the frame.

I would at least put a leveling laser on it. There are cheap on Amazon or at Harbor Freight.

I'll try the piece of string from there to the rear seat post, too.

Couple things:

Congrats on finding a motor. Way better way to go than fixing the broken bearing seat on the old one. Its (maybe) doable, but must be very precision work. Recommend to Use the good set, and pass the others along.

Fan should be bare aluminum, not painted.

Headset and frame definitley look tweaked. Def took a git at some point. Frame badge and steering tube races should be perfectly centered to each other, and centered to the rest of the frame as a whole. Its been hit and needs alignment, from what I can tell in the pix. As Rowdy said, check it with a lazer, or even a long straight edge laid lengthwise across the tank/frame

Thanks! That was miraculous. Finding an engine.

I was thinking if trying to save the original engine, but mostly because the SN is so close to the bike. The original engine is close to the frame (*12,xxx*), and the new engine is *15,xxx*. But the numbers aren't an exact match (I don't think they ever were for Vespas).

For the headset, considering getting the Euro version, which was the one designed for the bike.

But torn on whether to keep it an American spec Rally (which are pretty rare). In the US, you don't often see ones that have all the original US-spec parts.

The Euro ones look nicer. I could do the Hella bar end turn signals, and the parts like the headlight/ring are easier to find than the CEV ones.

I'll take more frame pictures! The frame is definitely needing some work.

The frame.

I placed a string from the seat latch to the center of the fork tube. Not sure if it says a lot.

The frame needs a lot of repair. But it doesn't look bent as far as I can tell.

It's very messy, with a lot of filler and paint covering some rust, and definitely needs a new floorboard and straightening in places.

I'm tempted to get it blasted, but might wait until after I remove the floorboard.

Just documenting my slow-going project. Ordering parts. Preparing for surgery.

While I wait for parts from Germany, I am watching YouTube videos.

This person makes welding stamped steel panels look like something I could do.

Haven't decided yet whether to use a welding shop. I think I might try to do repairs myself. But I've never done welding.

But I've watched enough videos to feel like I could.

It's amazing how these things clean up.

The carb/box had the remnants of gas from 1983 (yuck!) - all turned to this gel consistency. But the 2 stroke oil looked clean.

I have never seen this, but the carb looks warped along the top part above the float bowl. You can see light through the seam when it is attached.

Is this something the gasket will fix?

The slide moves freely. That's where carbs usually warp.

Is that a ginormous crack up by the swingarm there?

It's just a very strange place to put a seam in the sand casting.

It goes all the way around.

The casting is very rough on this one, and they didn't clean it up at the factory at all. There are a couple of razor sharp spots at seams.

I guess Giovanni dipped out to the bathroom when the quality check was done and let his apprentice Mario take over... friggin Mario...

That's a wild looking fake crack!
Glad that's all it is too.

A little bit of attention to the trouble spots.

These are difficult, bc it's hard to find a reference of what they should look like.

Some progress.

And before and after vapor blasting shots. (lots).

Few more. I post lots of photos.

Hopefully it's a good reference for what vapor blasting a vintage Vespa engine results are like.

Really happy.

It was done by Scooters Originali. They did a nice job. I shipped it there, and they had it back in a week.

Thanks for the pics and the examples of what vapor blasting can do. Very nice!

Thanks!!

I am taking lots of photos.

I looked around a lot for photos (and vendors) for vapor blasting. They're surprisingly scant. There was one place in all of Northern California that did it, and apparently they're out of business.

Scooters Originali did a nice job. That was $400 for all those parts.

It's definitely an improvement! Not exactly brand new looking, but I guess as close as it will get. It's pretty magic how it removes all the oxidation and darkened aluminum.

But like other blasting, seems to make the areas that were oxidized more visible. You can really see where they were degraded by the sun/water. But it looks all clean and healed.

Damage, or casting mark?

Cleaning up the front swing arm, and I'm puzzled by this one. It looks like it's made from two pieces cast together. The aluminum body, and a steel plate where the fork attaches.

Is this how it looks? Seems like there was more aluminum, that broke off.

But the fork pivot part is there.

And now on the to really gruesome part. The frame.

What's underneath a thick layer of bondo? Rust.

It's worse than I thought.

Still going to try to repair. But definitely a challenge.

I think the frame might be slightly bent. I need to check it. There's no crumpling in the channel, but it looks like the legshield was pulled away the slightest bit, making the spot welds dimple on one side. Or could be nothing.

This is the part I've been dreading, but ready to face it.

I'm going to get one. Will that tell me if it's bent?

I need to find a shop with a jig, and I guess need to know the correct angle of the fork tube?

I think the business has relatively new owners.

It's someone named Rob that works out of his home in the suburbs of Portland, OR.

He seems mostly to be importing Lambretta parts, and working on Lambrettas.

The old shop was in Philadelphia, right?

It almost seems like a different shop. But I was really happy with it. He turned it around so fast, and the parts he had were great. He had ricambi Piaggio and Dell'Orto gaskets.

Nice! I can take pictures of anything if you need.

The tail bottom (at least on My 180)
Was flat then curved on the back, but with a bump (like the legsheild) on the side. I spent waaay too much time on this so I think it's right.

Thanks!!

How did you end up fixing? You were missing some metal.

I had a question for you. What type of welding shop did you use? Here, there are ones that are like master welders, but mostly do things like furniture and stair rails. And then body shops, but those mostly seem to do rough work, or do like ferrari restorations, and are super expensive.

And with the frame jig. Did you know the exact angles for a vespa?

I found these photos of the tail, which helps.

Rough casting marks that were never cleaned up. I got a new front fork for the Allstate, an FAItalia, and it had the same rough outer cast stuff. I just filed it off clean and installed. All is well...

And I just saw the pics of the body. Bummer! Seeing that hurts....I feel for you....
