Very cool find , I wish it was mine .
I raced an 86 Honda 250R when I was 17. It was stupid fast. I had it when the first Suzuki Quadzilla 500 first came out, 88 I think. I watched a grown man cry when I whipped his *** on a 250R ( of coursse it wasn't stock....Paul turner 300 kit with piston pipe reeds and carb upgrade ) I think before that I owned one of every model made, but the Honda was definitly the fastest.
You just had to lean to make em turn...and never put your foot down , lol.
Hmmm , maybe a neat project.
