I'm a brand new KDX owner. Picked up a 1991 KDX200 with title this morning. I paid $800 (hope that was a fair price). So far, the bike runs pretty well. Biggest problems right now are leaking fork seals, and slow idle. She bogs a bit in 1st gear but screams in all other gears so perhaps the carb needs to be cleaned/adjusted?
Anyway, I'm happy to have found this site. I'd like to do a full restoration but not quite sure where to begin. The previous owner threw in an original maintenance manual which was a nice bonus. The bike has the usual wear and tear from use and age... a few small surface rust spots on the frame here and there, etc. Overall, I think it's in good shape. The compression seems strong, and no leaks or blown gaskets.
Here's a pic of my new toy!

P.S. Anyone know where I can source a kick-stand? Everywhere I look, it's out of stock and says the part is obsolete.
