I just picked up a Lifan(xr50 clone) motor that claims to have a fully automatic transmission. I have heard that these fully auto motors are actually just a single speed with an auto-clutch. Has anyone ever used one of these fully auto motors? I am building a Motoped that I want to register as a motorized bicycle and in California the transmission is supposed to be fully automatic. Has anyone ever ran into trouble running a semi-auto(shifter+auto clutch) in a fully auto state?
