Some Finnish engineer did this starmotor inside a back wheel of a motorsickle in the 1920's pretty dope innit??!! Check out the exhaust, it runs inside the wheel. The carburetor is on the other side inside the brakedrum. Last friday was cool. I went to Technical Museum of Helsinki and after that we had lunch at Beefy Queen (the name says it all) and after that had some beers at Bar Llamas. Good stuff all around.
