My brother had one of those, probably similar year model too.
We are twins so I rocked up to a servo one night to get fuel and the bike boys wandered over to ask why I was in the car...
One of them said to me that my brother was on a mission to get the most mileage from a front tire. My look of non comprehension brought the response that he never puts the f###ing thing down!!!
He wrote it off from co-incidentally a high speed wheelie crash...
They seem to have a certain addiction don't they?
