Modern Vespa

Believe it or not that is the original trim. It was pretty scratched up so I sanded it smooth and polished it - maybe too much.
I don't really want to get into porting and bigger carb, etc. I'm just wondering if there would be any noticeable difference by just bolting in a 130 kit (?).

Btw - what exhaust is that?

Maybe I'll change my mind and go nuts. I do need a winter project.

You could just bolt on either kit, but both would like it if you matched the ports better. The knock off kit still breathes better & makes more power. Here's how us cheaters do port matching: Cannot recommend...

Cliff notes:

How to seal up all the little cracks & crevices in my aluminum foil dam with candle wax. Note scribe lines from the gasket.


Open up, say"AWWW". Now spit it all out & thenyou can BREATHE.


And all cleaned up. Yeah the kick start is the way I got it, still there, starts EASIER and never hits curbs or big rocks.

The pipe is a good quality Simonini version of a common design kidney for smallies, many brands & some just crap noisemakers. I run the same Simonini and like the performance AND the sound.



The hi dollar Malossi version is on the bottom pic, @ Mercato who doesn't carry the Simonimi kidney. They do have a nicer Simonini I want again @ just over the Malossi kidney price.

Just wanted to share my recent smallframe purchase.

Its a V50 N

On the papers its says year of production 1965, but when I checked the chassis number online I got 1968.

Nice find. '68 is probably correct for this scooter. '65 was the last year of the small door model

New toy for restoration. It's for my brother in law. A 1981 Vespa 50S we got for a steal. Only 200EUR including the paperwork and license plate. Needs a lot of work though. Restoration thread coming soon, cause I'll also need some help on how to make it a bit faster...

Great find SaFiS. V oodoo knows most of the tricks to get improved performance for little cost.

The Grasshopper instructs the Master, sayeth the flea!

Nice try though, I am flattered and you are wrong.

Thanks!

Regardless, you just need a 90/100/125 crank and new primary gears. Pick a top end, & a pipe & a carb, maybe a clutch(I just use fresh stock) - match some ports... You know all this. Lucky dog you, it's already got 4 speed. Chris strikes GOLD, w/ papers in Greece is rare & no VERMONT to use. For 200 a killer deal, wish I had soma them papers .

Money is not an issue on this one, so we're already planning to spend 2k - 4k on it. I have a PK50XL2 motor for parts, so I'm thinking, cases, gearbox & rear hub from the PK, change the primary, Polini 51mm stroke crank, Polini 130 kit, a 24 or 25 carb and a race exhaust (will decide on it). Front from the PK and probably a disc brake...

Terry, this one came from Chios. Original color was yellow...

Since there isn't a set budget, maybe a 5 speed gearbox then? They look legit. The sliding shifter thing appears to be "Lambretta strong" since it has 6 legs instead of 4.

^^^ WHAT? Linky, please?

Too much money. Not worth it...

What's more crazy is that I think someone was making a smallframe 6 speed transmission a few years back. I don't know if it ever made it into production, but I think I heard about it in Scootering magazine?

Definitely expensive! But when compared to the Lambretta Cyclone 5 speed, you get lots more parts included with the BSA smallframe transmission. So based on the weight of steel alone, the Vespa 5 speed kit might be a better deal...

smallframe 5 speed- 1550 Euros
Lammy Cyclone 5 pro- 1150 Euros

Lots of Lammy riders are springing for the 5 speeds nowadays, so i'm wondering why there's no love for the smallframe 5 speed. Is it because the Lammy is a better touring (where the 5 speed might be more worth while) , while the smallframe is just too small (comparatively) to tour on?

FAIO have made a 5-speed smallie gearbox since I think 2011. Apparently they also made at the beginning a six speed for racing (actual racing, not the SIP kind ) but don't any more.

Hello Everyone,
Rebuilding my v90 with a Polini 133 cylinder, Polini crank, Polini IDM ignition, SIP Road pipe

I need advice on the Carburettor

What would you go with?

Polini CP21 clamp on style to mate with original intake manifold, eliminating all the stupid foolishness of the multi-part assembly with felt gaskets that leaks 99.9% of the time.

Thanks sdjohn I will check out that CP21

Today it was enduro day.

definitely like!^^^

Hooning this scruffy yellow 50 special offroad, what's not to like?


"Everything is going well, the scooter runs and makes me happy."

Really - why not?)))

Great photo roland87 I agree why not

Saw a post on FB Smallframe page showing the use of heat reflecting tape on the inside of the left door to protect paint from curley exhaust heat. Since I am cutting the battery box out to accommodate the PM Tuning Evolution exhaust I am using on the '75 V90 build I am doing.
From the color pattern on the tape seems like a good idea.

wow mayor that is looking fantastic!

I used that same stuff under the entire engine area to help with heat sink into the gas tank/ air box area.

scootermarc69

Great idea thanks

What's that fancy latch you're using on the door?

From parts. Mostly VMA1 with exception of round speedo headset. And the goodies.

Very cool!

new register!

Hello, great forum glad it didnt go the way of farcebook, like so many other forums

100Sport, rescued from a barn in about 2009 along with another 100Sport(blue).

had bent fork and non runner when pulled from the barn.
fixed fork in short order then stopped working on it while I rode the other (blue) for the summer.
moved houses, other projects, yada yada.

decided to get it running.

re wired stator, new points and new coil, fought timing.

it lives.

thanks great forum loads of nice info.

A temperamental PK. Perfectly timed. I was crying when I first saw the video...

https://www.youtube.com/watch?v=rKClk7zWl9w

hahaha!

Looks like a guy who claimed it ALWAYS starts with one kick. Because the kid is having such a good time! I hope that's not you... I've learned to add "usually" when/IF one does.

Now I hated my PK for just this reason, flip side. It NEVER starts easy cold with normal techniques! Gas on, 'choke' activated(fuel enrichener circuit that adds extra gas to the mix), throttle closed, twenty kicks plus every variation and not even a pop. Runs great, lots of power, winds up to the moon and starts warm fine. I would resort to squirting a little gas into open throttled carb thru a long thin tube. But I hated it and didn't ride it.

This year with lockdown etc, I was DETERMINED to do something about it. Rebuild carb AGAIN making SURE the choke parts are clean, clear and functioning mechanically as they should. But no love With all this effort, I was running no air filter, no seat latch in back and no tool bucket in yet. In desperation I flipped seat and stuck my middle finger over the intake (symbolic, right? ) only because it reached best and choked it the old fashioned way. Couple kicks later, she's purring! Now I love to ride it, click click click, single cable shifter for the win. 8)

So now that's my method and quite reliable, but Chris or anybody, PLEASE tell me how to fix this, it's rather embarrassing!

Hi all. On a Blue Badge smallie, how big is the actual blue badge? There are two available, 52 and 65mm.

This is not it btw, just for illustration.

Ginch,
Looks to be 65mm.
Hope this helps.

Thanks heaps Poidog, appreciate the advice!

How does it start with the air filter installed? Polini make a big one for PK https://www.treatland.tv/polini-CP-carb-curved-air-box-48mm-ID-p/polini-air-box-203.0015.htm
