I have four questions:
1 - How many spacers are in the front wheel? Right now I have two spacers in place and there is too much play on the axel. I have a third piece in my parts box that looks like a spacer, but not sure which side to put it on.
2 - What are these green and yellow wires with the open connection supposed to connect to?

3 - What does this green connector above the fuel hose do and where does it go? I can't find where to plug it in anywhere.

4 - On the front side of the battery box there appears to by a regulator/rectifier unit with a plug-in on the bottom. I can't find anything to plug in there. What am I missing?
Many thanks,
