BUILD DESCRIPTION

UpJet 103! I drove to NYC to pick this bike up, big thanks to Nick UpJet for holding it for me! Since my other 103's are all complex builds, I decided to keep this one simple, Crate motor bottom end, Le Partie CDI, 15 SHA, TSM head, in the pictures it has a Mini Circuit from DOS, and a Teknix cylinder, however I had a cheapo 6 port 50cc Airsal on the shelf, so I swapped to that with a Simonini Circuit I had laying around as well, modified the stock vario, and called it a day. Nothing fancy hear, just your basic 35-40mph Frenchie, reliable, and quick off the line, it will be one of my go to daily's for the 2020 commuting season. UPDATE y'ALLLL This bike was to slow, and at the time I didnt have any air-cooled fast 103's, soooo I tossed a Polini circuit, and a 64cc cast iron Malossi on it! a needed upgrade, now it does 47mph, still using the 15/15 sha, and stays well under 350 degrees (coooool for a 70cc Frenchie!)
