I have my Tanaka 40cc belt drive on a Ca 520 - 7 speed cassette
bicycle. I mounted my HP power pipe up to the Tanaka 40cc. There
was a very impressive power pick up at middle to high band with just
the stock carburetor. I have the HP carburetor and chrome air- cleaner
to mount to the engine at a later time.
The Triple V Rims with 14 gauge straight spokes with the Serfas Drifter
tires made for a very nice ride. Some joggers yelled for me to slow down
but I know that is the fastest I have ever been on a bicycle.
