Get her running first, then you can start working on the rest.
The bones are there for a fun little Café.
seriously? you know better than this. Unrideable pieces of hipster art bike shit are not welcome here. This literally looks like a collection of what not to do. I can't tell if you are taking the piss or being serious it's that bad.
Issac here are some realities for you:
- it costs the same to resurrect a shitty neglected cb125 as it does any other motorcycle including the big ones. Cables, brakes, service items, these things all cost roughly the same.
- This hobby is not cheap. If you build your bike properly (and by properly it is safe, functional, well constructed, and shiny) you'll probably end up spending three times what the bike is worth. actually probably more since cb125s are worth somewhere in the neighborhood of a used condom or already chewed gum.
- If you are "new" to everything you have taken on too much. You probably don't have the tools, the experience, or the skills to do this properly. most of your spending will be on tools and replacing parts that really you shouldn't have to replace (like those awful rusty wheels). It always pays to spend a little more money and get a running bike and cut your teeth on maintaining it and keeping it running.
- you picked a bike that has almost no aftermarket. Ebay is just about your only site outside of the general parts sellers that would stock you with oil and cables and such.
If you still insist on this project, get a manual, get some tools and focus all your energy on getting the bike running. Forget seats, forget bars, forget anything custom. Do not tear it apart or it will never go back together.
