My friend baught a Z50A K4 for his son to learn to ride on. He's doing great but it looks like the bike is missing some things. The side cover is gone and I'm not sure what it is suppose to cover? Battery? It doesn't have an ignition switch did these come with one? I see the wiring harness has the plugs for headlight and tail light but I don't see a rectifier anywhere. Were about to take the forks apart because they are wobbly (i'm thinking the plastic is missing inside the fork tubes) and are thinking about getting the lights back on. I looked at the diagrams on Dr.ATV and I dont see where a battery goes at all. Any elp is appreciated as I'm new to Z50's.
