Hiya fella from upstate NY.
I'm having trouble posting, or may have posted two or three times (think I can remove them if that's the case).
What I wanted to say was please keep the KX and restore it to original trim. There won't be many of these old motocrossers around in the future.
I'm new to the site too. Bought an'87 which is impossible to find parts for here in Mexico and people (understandably) aren't prepared to send stuff from the States. But when I get back to the UK I'm going to restore it back to original using as many OEM parts as possible. I'll probably sumo it to actually use it, but keep everything to convert it back in the blink of an eye. If I could buy a basket case (please note anyone in the UK), then I'd have a supply of mechanical parts and consumables for it for whenever I need parts. My thinking goes like this. In ten years time I might be too old to ride it, by my son will be 17 then and he'll be the proud new owner of a 40 year old, original spec Kawasaki KX500 motocrosser!
Try to restore yours. Please don't break it up (think you call it "parting out" in the US?). I'd love to follow your progress here on KXRiders.com. If not, Sandblaster would buy it. I know he'll get round to restoring it eventually. And the prices you pay in the US are ridiculously cheap compared to the UK.
Good luck mate!
