Built 3 or 5 of these motor bicycles always grubee skyhawk and all most done with the 5-6 build. i just need to break the chain add gas and oil and im done. Several problems i may encounter is how to install the wide crank pedals (how to do it) pull start doesn't really pull start like on outboards lawnmowers etc. is this normal? (jerky pull) other than that i should be fine pedal starting it but whats the point of pedal starting it when you got a pull start isnt that the point of these motors?
