One of my many V1 builds, this time around I found a 41mm piston and had a 25mph cylinder overbored to about 60cc, paired with a vm18 and a Tomos estoril. Its not terribly fast, but its quick and pretty quiet, great for ripping around our downtown area. I re-geared the snowflakes with a Sachs 38t sprocket, this bike hits about 40 and will hold it for as long as you like!
