Don't let the Sport fool you. This little Vespa is limited to asphalt twisting 25 km/h.

The mod hasn't started. To be accurate, the resto hasn't started either. To be honest the engine also doesn't start. To be fair that is probably a good thing, considering the mounting of the exhaust.

How did this little beauty come into your hands, I hear you ask.
I'll try to make the story short. Shorty before Covid my neighbours kid bought this little gem and used it for school runs. It only took him few months to have a little accident. Leading to his undesirable modification of mounting the exhaust to this jewel by a red ribbon (this can be seen in the picture I hope is attached). Since then this pearl has stood unmoved in the location shown. Rain or shine it has been standing its duty there, letting nothing stop it from not moving.

Then one day, as I was working on my bike next to this rough diamond rotting there and letting it get on my nerves. I coincidentally ran into the owner's father. As we chatted I offered him couple of hundred Euros for the turd. Mostly to be able to get it out of my sight. After some negotiation we came to an agreement of me paying him 50% more. Good thing I didn't have time to negotiate any longer, or it might have been even higher.

Now I'm facing a dilemma that I will explain in a later post.


The Sportiester. That number plate is a work of art. I did that myself.

I've no doubt that letting the exhaust hang ultra low and fasten it by red ribbons is the future. However, we are not quite there yet. So I plan on removing the ribbon and raising the exhaust.
Careful examination of the exhaust mounting strategy reveals that the exhaust is securely mounted to the exhaust mounting bracket, and that said bracket is securely mounted to the wiring loom. What the eagle eyed among you will also have noticed is that what it's not securely mounted to is the engine block. Where it should be securely mounted to the engine block is a rectangular-ish hole. This might cause a minor problem in the future.


Look at that little spider, all alone there. Hello, where are your friends?


The hole makes it not whole.

No worries I thought to myself. This is only one of three mounting points. Tack weld it back on, let the other two take most of the strain and strike this off the list. Well,,.
The second one is only half there. And the third one is a bit off.
It's no wonder. The exhaust seems to weigh half a metric ton. First I was seriously wondering if some previous owner had filled it with concrete. I've had liter bike exhausts that felt lighter than this, including the downpipes. Apparently this weight normal.


The second point. It's no point in trying to use that as it is.


The third point. That little nub in the center of the exhaust hole is probably one of the things the Vespa engineers put in in an effort to slightly tame the powerful thoroughbred horses that were installed in the engine in the factory.

I'm shocked that anyone thought that would hold??!

Perhaps it was just a temporary thing (to keep the exhaust off the ground whilst parked)... but something tells me that a logical explanation might not be the best. 🤣

So, is the rest of the engine case ok? Never quite realised they could crack like that.

The stock exhausts are very heavy. My aftermarket exhaust (although still steel) is substantially lighter. Kept my old one for bicep curls.

Okay. Let's check the damage so far (on the engine, the body/frame/etc. will be later).
I'll need exhaust and that, ehemm, 'little' piece on the side of the crankcase.

I cannot find a way simple way to position text under the photos (probably due to my advanced age). So I have to ask you to help by imagining that you're reading this part of the text positioned below the screenshots.
Like all the cool kids do these days I looked on the Internet for parts. It's easy. You just find the part on a drawing. Find the number next to the part. Use that to find part number and price. Then I did a quick cost calculation on the parts needed. Heavy two. Plus a large two. Equal a really big four. So big that my wallet asked if I was serious. If I needed professional medical help of the mind correcting variety.
Here is another one of those dilemmas I meant to mention in the first post (I just checked, I did mention there was a dilemma). My welding equipment can easily handle the exhaust downpipe if there is a half decent amount of material left. In emergency, and with great care, it can fill small cracks in aluminum. It cannot really create large structural pieces of a cast aluminum crankcase. It's missing the AC option, welders will know what I mean, and maybe tell me a secret way (taught no doubt to them by Tibetan monks) to get good results without that.
So the options I have left are:
- Buy a better welding equipment (my shoulder angel is shaking its head and frowning, but the devil on the other shoulder is grinning like a maniac).
- Trust a person I've never met, in a welding business I have not found yet, to weld the crankcase securely and cheaply. I guess I should add fastly since I'm asking for all those impossible things.
- Ask someone to allow a stranger to access his professional quality welding equipment. Since I'm dreaming here too, I'll ask for it for free.

If anyone can suggest good solutions (for example where I can buy just the small half part of the crankcase) I'll give them a compliment.


The exhaust. Here I need piece nr. dark spot. Eh. I guess I mean I need complete exhaust.


The crankcase. Here I also need piece nr. dark spot. Hmmm. I guess I need a whole crankcase.

It's not an easy thing to repair. The good news is that a friend of a friend of a friend of a friend knows a guy that has a brother that supposedly is able to fix the crankcase a good welder. Problem is he is very busy. I am not familiar with the general standard of the aluminum casting Piaggio uses for these crankcases so I don't know how easy they are to weld. The oily part of the engine is still pretty much sealed so in theory it should run fine. It'll just be a bit loud.

Good luck - I think the engine case is the most expensive part.

If you're able to, perhaps consider another donor scooter (they often come up as non-running project bikes).

Not sure about your bike - but my engine number is stamped on the variator side of the case, so swapping the stator side won't affect the registration documents. 🤞

Either way, it'll be a fascinating project. 👍👍

Teamwork, teamwork, teamwork.
To continue this assessment of this chariot of the gods. The front is next to be inspected. I suspect I should have started there, as it's always the first part to arrive at the destination. As I suspected there is slight room for improvement here too.

The front tire and wheel team are mounted to suspension arm (covered with still almost chrome (or satin, it's hard to say in this light, under this dirt) cover) that is connected on the other end (with barely visible breaks in the seals) to the tinworm colored fork, which looks to be exactly, no more, no less, as bent as it should be.

This is suspended by the spring that, through inspiring teamwork with the damper (and the aforementioned fork, and tire and wheel, of course), has kept the front from getting as fashionably low as the exhaust. Through the same teamwork it has also shared some of the tinworm with the fork. And the damper is oily. Oily tinworm is typically a very rare beast, as most oil types repel tinworm so they rarely share the same space.


That tire wear indicator is in a chasm. The tire is barely worn there on the edge. Also of note is how the fork is coated with this lovely brown tinworm (water dependent semi living invasive species that loves to eat bare metal, multiplies at high speed n


Look at the pretty patina on the wheel and the screws. Creeping tinworm here too, digging under the shiny red of the spring. Note how this beauty is equipped with a progressive rate spring. Nothing but the best is good enough.

Just goes to show that age/mileage metrics can be deceiving. Vehicle history is a key component to the general condition. 👍

Looking closer at the front end, it's "mostly" fine mechanically. The most pressing, apart from broken seals (no animals were harmed in the typing of this post), is the spring that presses the earth down so the body doesn't lie on the ground. Lying on the ground would cause friction as to prevent this speedy steed from being able to move. Tinworm in springs can cause unexpected high speed reduction in ride height (not unlike what happened to the exhaust), that can lead to another sudden drop, this time in speed, which can lead to the rider meeting the ground in undesirably uncontrolled manner. Unfortunately the spring is another of those "dot" items that is so integrated with the damper unit that it simply cannot be separated from it. They might think this is idiot proof, but I have some ideas for another time.
The tire is not as evenly worn as one would have liked under ideal circumstances. The wear indicator on the edge lives in a chasm, but the one in the centre has reached the point of wearing at the same rate as the rest of the tread. At least the wear there cannot increase. Which, as I wrote earlier is not ideal. This tire has served well for 10 years. It might be time to retire it and allow some younger black beauty to take its place?


Those front tire wear indicators will now wear at the same rate as the rest of the tire. Not bad for a 10 year old tire.


This brake handle has caught a case of the rarer silver tinworm. That one is a bit of a snob and never attacks the cheap metals. It has been slightly fooled in this case, since this is not highest quality CNC machined brake handle but instead lower priced

The trouble with starting at the front is that you can only go backwards. That's why I didn't start at the front. But I've covered the front and I'm going backwards. The left side is in pretty good shape and not much to say about that. The seat is comfy, without any damage. Little moss is growing, but that only adds to the charm.

The red accented white sport clocks are a beauty and add at least 0,15 hp to the power. That probably takes a whole second from the standing quarter mile. The fuel gauge is a pure luxury item. Back in my days we had a Petcock (one word, must be one word, I looked it up) to use when we ran out of fuel. The clock is there but has lost its ability to tell the time. I read that the batteries in the clock don't last long. First I thought that the battery was LR44 as in the little game computers like Donkey Kong. Post 58618 in this forum told me that it's (among others) a Duracell D386. Voltage is 1,55. That makes it tempting to solder wires to the clock and put AAA Alkaline battery where it can be easily replaced (similar to topic 147350 in this forum). Although that might be overkill with the likely lifespan left in this battered, hobbled, rusted, sorry excuse for a mobility device.

I keep typing longer text under the images than is displayed. I must watch out for that.


Seat seems to be in good condition. Just a little scrubbing needed.


Wow. A fuel gauge.
Oh look. The battery in the clock is flat. Which size is that? LR44? No, it's 386, like the processor in my first PC.

Now the rear. It looks pretty good. Still firm, without any orange peel. Just tiny tinworm spots here and there and tiny cracks in the plastic of the lights. Like spreckels of freckles and the tiny wrinkles around the eyes of a beautiful woman as she hits her 30s.

The rear tire has lots of tread left in most places. Like the front is has some localized wear. Unlike the front it has been replaced at one time. Oh, and it's flat. No pressure there.
The black variator cover has been invaded by the fancy tinworm and is now mostly grey/white (or gray/white if you live in the colonies).

Added a photo of restomodded Sportster that I spotted in the village. This has some of the things I'd like to do to mine.


Plenty of wear left in this tire.


My Sporties long lost twin. This one has visited the plastic surgeon. Gives me some ideas.

Well, well, well. That is basically it. Preliminary inspection finished. Some little rust damage here and there, as can be expected for a 10 year old. All is good.

Wait a minute. I forgot to look at the bottom of this shiny foal. Since it's a unibody, not a bunch of plastic on a pipe frame I better look there too.

I guess I'd better have a chat with the doctor about some heart medication. This could have gone better. It's starting to look like the engine is the lesser of two evils.


Hey, look at my Honda in the background.


Under closer inspection it's not as bad. Well. That's a blatant lie. It's even worse under close inspection.

Phase 1. External examination of the Sport Pony is complete.

"They said it couldn't be done. They might be right." Nik Blackhurst.
Truth be told I was about to cancel the project. But I found a cheap broken engine, containing one piece exhaust and unbroken exhaust mounting points. That can be combined with the original one I have to make a nice working powerplant. Dash of work and then worry about the chassis. Which is my big worry right now. That underside is a lot of little bit past its prime. And seems to have been lacking some primer. We'll see this better once I've sanded the paint off and gotten better look at the condition of the sheet metal and ease of access to weld patches in if needed.

Onwards to Phase 2. Teardown (and I hope it will not be tears down) to start next week.

What to expect under the plastic covers. Shocking amounts of (c)rust under the paint on the otherwise nice metal. Stuck fasteners, leading to broken fasteners. Worn moving parts. Broken mounting points. Split seals.
I have removable energy storage container rotating electrical apparatus, whose extruding part can convince most stubborn threaded carpenter nails to change their mind. If that is not enough, I also have mains connected sandpaper equipped fast rotating disk electrical apparatus to nudge them further.

Aren't I forgetting something? Oh yeah. In light of new previously unknown project downsides, on the downside, the previous owner is dropping the price a little.


Good news. The barn door cleaned up okay.


Borrowed a storage master key from Mr. Wong at the Chinese Dragon.

Let the dismemberment begin. Like every good builder we start at the top. Off with the screen. Only four screws and the screen is off the mountings. Then two more to take the mountings off. Looking back I can clearly see that it would have been easier to remove the screen with the mountings. But we don't remember, or learn from, the easy stuff.


I seem to have misplaced my round screwdriver.


That sticker came off easier than expected later on. If I remember correctly.

We meet again.

Under the screen we find the light. Behind the light we find connectors, and I must admit, a little bit of rust. Nothing serious this time though.
I've been debating LED conversion by bulb replacement. Light replacement would work too, but could cause some fitment issue. It's difficult to find square LED headlight. Why would it be called a "headlight"?


I've been expecting you, Mr. Bond.


Let's shed some light on this matter. Too obvious?

The turn signals are off, and off the scooter, as are the clocks. The clock in the clocks is also off. It's not clocking in. It needs a new battery, but not the same battery as the rest of the bike.
Life is complicated. How can you tell if a turn signal is working if it's off half the time?


The clock in the clocks is not working.


Turn signals look okay. Little moss, little crack, not that crack. Maybe fill the little crack with CA, not that crack.

Onwards with the off things.
Now more plastics to come off.
The screw that just spun around, around, like a record baby, came off in the end without any parts being damaged. Or more accurately, more damaged.

Am I boring you? Just let me know and I'll stop.


Lots of wires. A rats nest of wires. A spiders nest of wires. It's not that much. It's Just few wires. This is what I like about this chariots of the gods. Simplicity.


That screw just rotates without coming out. Unfortunate.

I think for all models, it's nice to see disassembly (with lots of pics).

You never know what happens to a bike over the years though, so it's a shame new bikes don't get taken apart like that - that would make for a much better reference.

Still, I'm sure most people would be able to tell that red ribbons aren't standard. 😂
