Sorry, but your 2 to 4 stroke upgrading idea won't work for many reasons.
The 4 stroke kit from Bicycle-Engines.com has the Much better Grubee 4G
gearbox than the chain drive pocket bike boxes used with the Spooky
tooth or BikeBerry kits and is only $30 more.
the Spooky tooth or BikeBerry so called "5G" gearbox has no relation to
a Grubee 4G T tooth belt gearbox.
There is no such thing as a Huasheng flying horse kit.
Spooky tooth and BikeBerry are the same company based out of Brea, CA.
