The hard-tailed part was extra info,kinda like those word problems in school. What I should have said is,I have a rolling chassis and motor and that is all,I got it cheap and am just going through it to see what all I will be needing to finish it..I didnt tear the bike down so Im still learning what all little parts I need. This is my first time to build a bike. So..From the diagram it appears I am missing some stuff,specifically the speedo drive and a spacer on the right side. If Im not running a speedo how do I take up that space?
