Wish I'd kept it, but when I later bought a new bike, there was no way I could afford to get the knew one without selling the old... :'(
And don't forget, mid-late 80's was when dirt bike prices went through the roof - most guys were struggling to afford a new bike each year, let alone keep an old one as well!
Hopefully that old U is keeping a smile on somebody's face in Sydney still.
Last time I saw it, Mark Avards brother had borrowed it off the floor of Action Suzuki to ride a Cross Country on... An 88 model YZ against a field full of 92-93 model bikes in the expert class and it still got the holeshot by a fair margin...
