The fact that you know two or more languages is impressive. You don’t have to apologize for anything.

Great to see a rotary valve being used. There's more than one way to skin a cat! Brilliant video.

Like an old Can-Am, rotary induction

Madness, that's some work gone into that

Very good work and idea behind to get the Max from most original

Epic!

That’s a cool sprinter motor. Wonder if anyone is tuning the Quattrini 244 by mounting the reedvalve to the cylinder like the m1xl?

watching what the Germans have been doing in the scooter world and particularly with the vespas you have to give them that nod of respect,the one men do without a word that conveys what would take paragraphs,.custom paint though,for me "clockwork Orange"early 80s started it and"Dazzle",was the pinnacle of the,made to show,gold plated and engraved block,but know gearbox scooters..trying to think of a Vespa that was up there,"script for a jesters tears",anyone?

Wish someone would make a ktm550 2 stroke cillinder or a 700cc 2 stroke skidoo cillinder work with lambretta engine case that won't cost 3k + 😂
