I bought an 86 a few (5) years back. I had to change the head shortly after because I could not adjust the valves anymore. Only showed 27,000 on the clock then but I am beginning to wonder if it had turned over once.. I contributed it to the early head and soft valves at first.. Now with close to 60,000 showing it is using about a quart to a 1,000. It runs great,fast,great throttle response and such. I only put on about 4-5,000 a year here in ND so the oil usage is more of a nuisance then anything. When a decent used one comes up for sale I will prolly buy it and transfer all my farkles over. That said I have gotten a lot of bang for a $1500 bike and have no regrets thou it sounds like an oil burner is a rare one.
