*oil change reminder*

This little PK runs really perfect without any troubles. It is nice daily scooter and always ready to go. I love it more and more.
So I already done 2000 km since bought her and 1700 km after I threw in Malossi 112 kit and 4 speed gear box I decided to change gear box oil.
I use 300 ml of 75W-85 full synth.
Now it is 47500 km on the clock.

Lot of times I had lack of luggage hook under the seat. I don't want to drill frame.
But yesterday I noticed there is two holes on the nose of seat I never saw it before(for sure I often see V-range on pictures with hooks attached on the nose of seat)

I remembered that there was a hook lying somewhere in my garage. It is plastic I think same as on my LML. Not the best quality but it free.

So now the Snowball became more practice and styled.

Yes mate. But this seat was on my 50 Special and it have hook on the frame so I never even thought about put hook on the seat.

This is what I've done, too. Otherwise, I'm always worrying a little bit that I'm going to come back and my helmet will be gone.

I've now drilled three frames to make it happen and while I always hesitate a little before I do it, once it's done, I never think about it again.

On the technical side, it was not a problem for me to drill through the frame. But I really wanted to keep more authenticity in this PK, maybe that sounds ridiculous to someone. I want that it look close to original. It is hard for me to explain it with my bad English.

But I don't like how the V-range hook looks on the PK frame. A few of our guys have it and I don't like it at all.

All goes ok. Started from second kick always. And I go to work on PK almost every day and every ride brings smile to my face.

Yesterday I looked on spark plug and it seems bit lean as for me. And I also don't like how idle jet feels too.
Now weather become really hot and as I ride very often WOT then bit richer main jet will not be superfluous.

So I decide to spent few hours playing with carb.
Changed jets few times and go for test rides.

Now it runs noticeably better with 105 main jet, 50 idle jet and mix. 3.5 turns out.

I also swap front tyre to Heidenau K38 3.00x10. Vespa has become more playful and sharpie. Much better than with Michelin City Grip Winter 3.50"
And finally I mounted MRP floor luggage hooks but I had to modify them with a dremel.

Just photos from jets test ride.

No. The distance between mounting holes was too small to fit PK. And a classic -
SIP listed this hooks as compatible with all Vespa models To be honest it was fit bolt-on on my 50 Special before.

Those plug pictures were way too lean. Glad you upped your main before Bad Things happened.

I have different MRP hooks on my Smallstate and I think I had to Dremel them a little, too, before they fit.

Last two days I was trying to sort out indicators problem. Sometime it work, sometimes not. And I noticed that it works not one by one but both blinks together.

At the end I just disconnect all that crap and connected only original relay from my P150X. I was surprise that indicators work as it should.

I also found original voltage regulator from PK 50 XL in my garage.
Interesting that lights and horn working without voltage regulator. I don't know is it really need but why not?


Now all look better. And work as it should.
As I mentioned before electric moments for me is absolutely nightmare. So this small victory is for sure funny to someone but it is a big pleasure for me.

Today I did a little cleaning in the garage and found original indicator relay bracket from my Nuova.
So I redone things again - third time for few days And now it look even better than before

I also found three nice original bolts, give them good cleaning and used it for spare wheel holder. Nothing special but I was happy by it because this PK have much more original parts(small and not so small) than on my other Vespas.

Just found another fancy part - original T5 wheel cap. It also came with my Nuova.

I like how it look and hope one day I can find another one.

Now in doubt - do I need to restore it and give it fresh paint or left it as is?

Today I took PK for a short ride and noticed that idle is too high. I not rode it for maybe two weeks.
I took spark plug out and WTF? Very lean(?) But before it was really good.
So I checked engine everywhere - absolutely dry and clean.
Checked carb and it turns out that the clamp bolt is untightened(IMO)
I also changed idle jet to 55. And it seems for me that main jet is also bit lean(105 now)

Yes rotary. And pad is in perfect condition. Carb have Polini air box, when I clean it takes 4-5 days to (I think) it fills with mixture and then it starts to leak inside frame(or from tube now)

You know I'm not a super expert, but that much blowback I would expect there's something not set properly.

I'd look at intake opening and closing, exhaust and transfer timing, ignition timing, and over jetting.

I remember opening the exhaust port to a higher timing and extended the blowdown timing because of it, I had more blow back from the carb. Also extending the rotary pad had the same effect… I didn't match with the exhaust timing that time, so more blowback was expected.

Current setup with Malossi 112 is fun.
But not enough. Especially after I'm tried my mate's PK with Polini Mono 130cc. So smooth and good torque.

So I think about 51mm stroke. Nothing extreme - I want that Snowball will stay daily simple scooter.
I will stay with SHBC 20 carb and original ignition.

For very good price I can get this SIP cylinder which is the same as VMC GS 125cc, only have smaller exhaust port and reworked foot so can be mounting without ignition dust cap cutting.

Also wondering what is difference between this two Mazzucchelli shafts:
Racing Crankshaft MAZZUCCHELLI
and
Racing Crankshaft MAZZUCCHELLI RACE

As for exhaust I'm looking on new Polini Original

Please share any thoughts and suggestion about my plan.

Winter is here.
So Tucano Urbano muffs and winter tyre is on its places.

Michelin City Grip Winter 3.50 on the rear and IRC SN26 Urban Master Snow Evo 100/90 on the front.
I tried few winter tyre but IRC is absolutely the best for our winter conditions. I just can't squeeze 100/90 on the rear.

Got early Christmas presents.
Mazzucchelli crankshaft, VMC short 4th geartree and SIP 27/69 primary. To be honest was impressed of finishing SIP primary seems much more accurate and fancy than RMS or CIF and with very nice price($27 with my discount).

Still in doubt about cylinder and exhaust to choose...

Very interesting kit for sure.
But I'm bit afraid of aluminum cylinders at all and especially how CP58 about cooling... One of the main advantage of it - 50cc cylinder cowl - absolutely not needed for me, here is no any problem with police if you ride tuned Vespa. Also for mounting CP58 is need to remove the ignition dust cover from the case, what I absolutely don't want to do.
On the other side price is $138(but still N/A on SIP) is very good comparing to other kits I'm thinking about:
SIP VMC cylinder($132)
Polini MONO($177)
Polini Racing($192).

I have 50 Special and P150X for some more fun or long road trips, so I want this PK something more conservative, relatively inexpensive, fuel friendly🤡, factory look, calm and soft scooter for commuting or for lend to a friend for weekend.
I even think about DR130($106) but rather no
It will stay with SHBC 20L carb, rotary intake and original ignition.
As for exhaust here is:
Polini Original($109)
BGM BBT($127)
SIP Road Banana($97)
Or even Sito Plus($60)

Yeah I think the cp58 would be a bit of an experiment. You'd be customising a bit too.

Just received SIP cylinder kit. Looks same as VMC/Egig/Italkast.

Bit confused of how rings locks placed. Then googled and saw similar on lot of other kits...

Marks on the cylinder wall. Can't feel it with nail or sharp plastic stick.

it seems nuts to put the ring gaps on top of each other. in what world does that make sense?

IDK.
ITALKAST, VMC GS 132cc, VMC CP58, VMC T-56 have the same.

Yup, its common now...

The Egig 170 piston v2.0 from meteor the pins are in the centre...

the v1.0 the pins were either side of the intake ports which is more traditional, had problems catching between the intake and transfers

Seems to have no problems with compression... apparently can survive 10000kms of casual riding around.

need to hone? and chamfer the port edges?

I recently discovered this cylinder: 144r ELLEZETA

I think it cost around 800euros... about the same as a Barone?

The exhaust port is insane... i think 2L tech and dexter exhausts currently fit...

No need to hone, but need chamfer for sure.

I'am also interesting what is right mount position for these cylinder head nuts? There is no washers and spring washers in kit. Do I need to add it?

I'm guessing "left" photo is the top of the nut… the threads all on the stud…

That's weird there's no washer or spring washer. I think they're imagining you reuse your old ones.

Who's the piston made by? Can't remember the name… not meteor…

Begins with "W" I think: found it… it's wossner
