Found this on Craigslist looks nice.
YZ490
"I don't wanna die." Hahaha! He's got that right. My 1980s race buddy had that same year. The rear end caused him to beg for a spinal transplant. The pinging sound that bike made after it got hot was only outdone by the blubbering.
I will say this though - that is a nice example of that bike.
My lower back just popped out thinking about all the vibration of that beast...
Ouch.

I used to race with a friend that had a 82 YZ490. My biggest memory is him always having problems getting it started before motos!
