I guess I'll chime in on this, seeing as I have a crapload of old Hondas.
The bike is worth 1400 MAX.
Non original motor, missing some odds and ends, repaint, etc.
Start it cold and listen for rattling noises or metallic tapping inside the engine.
DO NOT buy if there are any noises internally.
Rev it slightly and see if the revs drop immediately to idle or if it seems to float around before settling. Indication of imbalanced carbs.
Not horrible, but you can use it as a bargaining device.
It had better run like a top and be completely sorted out for 1400.
They are nice to work on if you have experience with multiple carb engines.
Very trouble free and easy riding.
I wish you luck in your purchase if you choose to buy it.
