Well I dove into the deep end yesterday buying a semi-basket case "school bike" CBX with only 4 miles (!) on the clock. I guess these bikes are still out there!
It's a 1982 and while the frame of the bike has sat outside and gotten a bit beat up, the entire top of the motor is still in a box. Paint looks near mint. Lots of what appears to be NOS bodywork and tons of other new bits in this treasure chest.
I'm still in the process of getting all the parts and the bike itself moved to my house, sorted and inspected. The bottom end of the motor sat out in the open and it was buried so far in the back of the shed I couldn't see the crank...it's my main worry.
The top end looks unused though

Got both sets of original pipes too (a tad rusty, but no holes or anything..), full service manuals, parts list and tons of NOS gaskets, cables, etc.
I'm going to get everything looked over and will want some help and forum wisdom deciding what to do with the bike: fully restore it (not so likely), partially restore it and have fun with it, or part it out.
I'm no mechanical genius, but I'm not a complete noob to the world of working on bikes. Obviously having my first major rebuild be a 6-carb CBX might be a bit challenging, but I think I'm up to it.
More info coming soon...
