You don’t mention whether it is a 1 or 2 speed. Also, your statement "But, if you pedal start it off the kickstart it will run up to like 40mph" doesn’t make any sense. What do you mean by the kickstart?
I meant kickstand, as in pedaling like a bike then throwing in the clutch
It is a 1 speed
Where does the black wire hook up on the wiring harness?
I don't have an on/off switch, I have a momentary "on" button kill switch , but I don't really need one yet since this moped won't idle. THat is the yellow wire, where should that wire go?
Anything not clear?
