Like many of the car magazine stories this feature is packed with tuning info. Kinda sounds like the 1955 frame is from a T110 as the front wheel is from a '55 T110 too. The '54 alloy 500 engine is highly tuned and the GP head is too cool. What a bad ass American Clubman Racer.
The Show & Go Cycle Shop is my private two car garage located in the foothills of Central CA. I am building everything from early Desert Racers - Street or Strip Dragbikes - 1960's Style Show Bikes - to 70's style Radical Choppers. Specializing in Pre-Unit construction 650 & 500 twins and vintage aftermarket parts identification. Buy, Sell, Trade, parts made by Webco, MCM, MCA, Bates, Flanders, Wassell, Superior, Routt's Cycle, etc. Period photos wanted. If you have stuff for sale related to what you see here email me. I will post pics of my projects from time to time and keep an ongoing thread of pictures and old magazine articles featuring modified British Motorcycles from 1946 onwards.
