Mine Athena crank is still in the box on the shelf. And it will stay there a bit longer.
Indeed this looks of, but not uncommon in the world of Piaggio/Vespa. It is known Polini cases and Malossi as well have problems with a flywheel which in combination of an aftermarket crank will scratching the cases. Try the new Pinasco flywheel and it’s even worse. Another option is mill something from your flywheel so it runs freely.
I thought you said building was the most fun? 😎
Maybe it’s best for it to stay in the box and look good. 🙂
Building is one thing and paying top dollar and having to “fix” it is another. 🙂
Sometimes I just want to invest my self out of a problem, instead of building it from scratch. But I expect the parts to be within decent tolerances. 1mm off compared to original crank isn’t acceptable in my opinion, and I don’t want to modify other good parts just to fit a faulty part.Damn, i feel anxiety when something comes out 0,05 mm off spec, I wonder how theese guys even can sleep at night when having 1 mm as tolerance during quality check. 😀
I’ve tried both the OEM flywheel and Pinasco, they both get stuck. I have opened a ticket from the shop I bought it, see if they’ll accept the return.
Have you tried the original flywheel, to check if you have less vibrations?
The Vespa engine uses the flywheel as a part of its final balance factor, because the crankshaft has the rotary inlet cutout where the counterweight has to be.
To my understanding, the pinasco flywheel is neutrally balanced, the original ones aren’t.And btw, i only buy Mazzucchelli crankshafts, never had any problems with them. The standard one (AMT002) will give you about 172° of inlet timing in a Speedengine. Runs fine like that, or expand it a little to ~185° or whatever you like.
regards, CarstenIt’s been a while since last.. Worked with the engine yesterday and made a Pull-start bracket.
The bracket that came with the PVR pullstart isn’t compatible with my CNC case.Further I shaped the transfers, not completly satisfied with the design but I think it will be good enough.
Still some work left I need to do with the dremel and polish it up a little bit and so.
Nice progress, its really getting there
Good to see an update again. Nice 😍

Gele RacefrikandelNice man , so VCM 2020 its will be on display
Case closed!
And ? is the crankshaft turning smooth ?, how is bottum and top dead center ?, is the squeeze oké !!
You can always work with different thickness gaskets for the right timing
Great Pictures, nice work, beautifull engine 😛TICKLING BARNOh my god, this engine.

Gele RacefrikandelVery very Nice! , love to see this one flying
and also a HK 2fast on top of it all ! You have any idea what kind of transmission you’re going to use with this kind of power ?Uppgraded to hydraulic rear brakes.
Not the Italy version, but instead the German version which gives the oppertunity to use rotors made for example KTM, Husqvarna, Husaberg. I went with Brembo originals.
It’s been a while… 😛
I did some minor adjustment, ditched the VHST28 and AM6 Vforce. Adapted the engine to KX85 Vforce3 with VHSH 30mm carb.. Dyno the engine to 27hp on the rear wheel.
Tried on 201 meter, but the cylinder studs that goes through the carter also transported cooling water into the cylinder, so the engine ran very badly.Now I have sold the 70cc kit.. Adapted the carter for 2fast 100cc crankshaft and 2fast 100cc cylinder.
A small video.
Op een of andere manier is dit topic mij helemaal ontgaan de laatste tijd.
De brommer ziet er erg gaaf uit ik hou van de rauwe look. Ik hoop dat we ook nog een fly by video te zien krijgen. 27 pk aan het achterwiel met 100cc is heel veel.Ik zie ook je CNC werk, dat is echt uitmuntend ik heb me gelijk geabonneerd op je youtube kanaal.
Wat voor freesmachine heb je omgebouwd tot cnc?Ik zou heel graag meer zien van je werk hier op het forum.
På något sätt missade jag den här tråden helt.
Mopeden ser riktigt cool ut, jag älskar det råa utseendet. Jag hoppas att vi får en förbipasserande video också. 27 hk bakhjul med 100cc är mycket.Jag ser också ditt CNC-arbete; det är verkligen enastående. Jag prenumererade omedelbart på din YouTube-kanal.
Vilken typ av fräsmaskin konverterade du till CNC?
Jag skulle gärna se mer av ditt arbete här på forumet.
