This is a video with max 170,min 40, needle k37, ramair

yes ramair, take in account that i live in Greece, where the air density is greater than Germany...I think that you have the problem of being too rich at lower rpm's, right....try 40 min jet, is the one zirri recommends...

the idle jet of 50 is too rich...try 40 with b40 emulsion tube...the needle k57 is good for this setup, do not use k30 as is too lean in the lower range...

Hallo, was Hauptdüse verwenden Sie?

hallo, Ich habe eine M1L und wollen einen neuen Vergaser zu kaufen, was empfehlen Sie? Dellorto VHSB34 oder Mikuni TMX35, ich will nicht koso .... Vielen Dank

I see more people having the same problem with vtronik and M1L setups...I believe that zirri must make an official answer...sorry for the english

what is the cost for the "cnc motor"?

Actually the broken crankshaft is not the DRT one is a Mazzu! He explains it if you read carefully! Also says that in his new project also had a mazzu and also broken again after just 1 race !!! DRT has not experience he admits...

Have you tested this crankshaft, cause I read second thoughts from a british racer , Tony... http://davedaniel.proboards.com/index.cgi?action=display&board=technical&thread=8203&page=1#70813

Thank you for your answer, as you understood, German is not my native language, but I tried to respect it and ask in German! I am from Greece, and unfortunatelly very few people here are familiar with these modifications, so I must seek help to elsewhere! So you suggest the Mazzuchelli, right? I will wait to get recommendations from other guys, as I as thinking of buying some other DRT products and buying the crankshaft from them as well, but have not read about their fame in crankshafts, as I have for falc,polini, but they are far away from my budget... Regarding DRT crociera, I have the 50.2mm version, I know that, tnx...

Hallo an alle! Ich habe die Vespa 50 Special '78 Modell. Ich möchte von Ihrer Erfahrung, was die beste Übereinstimmung für dieses Kit ist zu fragen, 1. albero M87 Zirri (210eur)(Muss ich den Fuhrmann zu modifizieren, um fit oder seine Ordnung?) 2. DRT Kurbelwelle 51mm/97mm (140eur) 3. was Sie sonst noch getestet haben? Eine weitere Frage, kann ich ersetzen die Standard-kreuzförmigen mit DRT-crociera, oder diese ist kompatibel mit DRT Getriebe nur? Vielen Dank im Voraus!
