Two 238 cylinders is crazy

[@carlmarkwyatt]

That's mental, I'd probably automatically go for an overtake if I saw one of these on the road only to be left behind in a fog of two-stroke. Brilliant build.

[@Lambretta-Lutz]

Haha, thanks! It’s a total blast to ride. You'd love the power - it leaves most people in the dust! Appreciate your comment! Cheers, Lutz

[@richardcarey169]

Power to weight is insane😊

[@Lambretta-Lutz]

That's why I went with a 23-tooth front sprocket to keep it somewhat rideable. But even then, if I give it a bit more throttle, the front wheel lifts even at 130 km/h in 3rd gear, and that's not even at full power... crazy stuff! This isn't scootering anymore - not at all...

[@Lambretta-Lutz]

In total, over 450 dyno runs preceded this... Among the challenges was ensuring both ported cylinders used had exactly the same power output curve... The stability of the stroker crankshaft was/is another ongoing challenge... Insgesamt sind über 450 Läufe auf Dyno dem voraus gegangen...u.a. war eine Herausforderung, dass die beiden verwendeten und geporteten Zylinder exakt den gleichen Leistungsverlauf haben... Die Stabilität der Stroker Kurbelwelle war eine weitere Dauer-Challenge...

Capito, è come quei distanziali dei carter motore che vendono (Fabrizi o Spricati ) per modificare da mono a bicilindrico, ovviamente con un albero motore dedicato a quella modifica ... bella bestia!!! Un saluto

[@Lambretta-Lutz]

Non era però un Plug&Play in questo caso... Con il P&P si possono aspettare circa 45-50 CV a seconda del cilindro, il che è già davvero buono. Per aggiungere ulteriori 25+ CV, tuttavia, sono necessarie ulteriori soluzioni per la trasmissione e la trazione. Il problema più grande alla fine non era come previsto la frizione, ma l'albero motore. Fino a quando non è stato abbastanza stabile per trasmettere senza danni questo massiccio momento torcente di oltre 60 Nm, è stato necessario ricorrere a soluzioni molto ingegnose...

So cool 🤯

[@jimsregaturntableshifijukebox]

Excellent work my friend and the scoot looks and sounds fantastic 👌 Jim🏴󠁧󠁢󠁳󠁣󠁴󠁿🙂

[@Lambretta-Lutz]

It doesn't just sound fantastic - it is a hell of a beast to ride... and that's with the tallest front sprocket available (23t)!

[@jimsregaturntableshifijukebox]

@@Lambretta-Lutz nice!!! 👌👌👌

[@gunnar9702]

You're definitely going to crash into a small child at high speeds in that thing and open up a portal to another dimension. In case you didn't understand that reference, I'm retarded. Sounds absolutely amazing and looking forward to more seasons

[@Lambretta-Lutz]

Haha, thanks for the hilarious comment! Glad you enjoyed it. I'll try to avoid any interdimensional incidents! Stay tuned for more updates and adventures. Cheers, Lutz

[@marcellocoppolecchia3046]

Ho sentito di una Lambretta con motore Yamaha RD350 ... È la stessa?

[@Lambretta-Lutz]

No, non è un RD o un motore da moto. È in realtà un motore bicilindrico basato sul blocco motore originale con una cassa di espansione per il secondo albero motore. Anche i cilindri sono pensati per la Lambretta. La cassa di espansione è disponibile come kit da STF in Italia (stflambretta.com/prodotto/kit-conversione-bicilindrico-chimera-carter-grande-200-225-250/?lang=en)

[@MX-fo2nu]

Das ist ja TZ 250 350 Power! Gute Arbeit hab auch vorherige Videos gesehen, da steckt Arbeit drinn mit Erfolg.

[@Lambretta-Lutz]

über 450 Dyno Läufe! Wenn man die Einzylinder Test mit berücksichtigt um 2 identisch geportete Zylinder zum Twin zu haben. Die schwierigste Herausforderung war die Kurbelwelle - am Ende muss die letzte Wange die über 80PS Wellenleistung an die Kupplung liefern, ohne sich selber aufzulösen...

[@MX-fo2nu]

Ja das ist noch mehr Arbeit als ich vermutet habe; und ja die KW ist der besondere Auftrag hier. Viel Spaß mit dem Gerät

[@MrClivehill]

I'm scared watching it, I also know Chris Sadd, who is a reknowned scooter engineer,andseen some of his work, but that's mental, if I ever meet you, don't worry I won't be asking for a go, very impressive.

[@Lambretta-Lutz]

Glad you find it impressive. If we ever meet, I'll make sure to show you more of the details up close - no test drive needed, but you still could ask for it ;) ! Cheers, Lutz

[@MX-fo2nu]

Extrem ;-)
