So I'm a noob.  Just bought a 73 CT90 and am working it over.  I'm starting small.  

Here is what I did this week:

1. Pulled the carb off and cleaned it out really good.  
2. Pulled the exhaust system off, cleaning and will replace some rusted bolts/screws.
3. Pulled the horn off in anticipation of a new one coming form DrATV.
4. Pulled the throttle cable and realized I'd bought the wrong one from eBay. Doh.
5. Pulled the gas tank, am working on POR15 for it and the aux can.
6. Pulled the rack off and had my boy work at the rust underneath it.
7. Pulled the kickstand and foot peg assembly and cleaned it/painted it.
8. Put a new tail light on.
9. Changed the oil.
10. Cleaned a bunch of surface rust from all the chrome parts.  It wasn't too bad, but it looks alot better.

What is next up:

1. Replace fuel lines and inline filters.  
2. Gotta figure out how to change the bulb for the Neutral light
3. Going to repaint the aux gas can.
4. Replace the air filter
5. Install new battery
6. Replace 2 broken spokes on rear wheel
7. Replace both brake levers
8. Install new carb PZ19

I'm going to be looking for someone local to help me with a few other issues once I get the above done.
