I remember reading about this hillclimb monster in the Streetfighters hard cover coffee book (http://www.trademe.co.nz/books/nonfiction/transport/bikes/auction-437746670.htm)
ReplyDeleteYou're right, the bike was made by its owner to participate in races uphill in the mountains

ReplyDelete..e lavorandoci un pò potrebbe diventare anche bella oltre che efficace!!
Le teste Feuling 4v hanno sempre dato problemi, anche e soprattutto a livello di aspirazione, con la plenum chamber, sulla quale potevi montare due carburatori ai lati opposti del motore (il kit prevedeva due Dell'Orto). E la distribuzione, made in Rivera, faceva saltare le punterie iderauliche ogni 3x2. Interessante, ma poco godibile.
ReplyDeleteI've read several just right stuff here. Certainly value bookmarking for revisiting. I surprise how much attempt you put to create this kind of great informative web site.
