Here's the deal; I went to look at the 91 today. It actually only had 37K on the clock and looked fine (mostly, it has been stored under a cover for the last 6 or 7 months so it could sue a good cleaning).
Most of the electronics seemed to function (didn't get to check the cruise). After looking at it, pretty much all the fluids need replacing - oil, brake/clutch. It failed the sizzle test on the right front exhaust and sounded like it was lumbering so it was definitely running on three if not two cylinders (didn't check the rear engine exhaust). As I test rode it, issues began. The owner put in fresh gas last night over whatever was already in the tank and my guess is that complicated whatever carb issues already existed. It ran for about 6 or so blocks and then began spitting and sputtering eventually dying out. At that point it would start with the choke and run, but not take any kind of load - it just died if you gave it any gas and/or tried to go running on the choke. Additionally, it wouldn't run at all without the choke. Fortunately, I noticed all this early and started back towards the owners house - almost made it.
Anyway, I'm thinking rebuilding the carbs, syching them, and fluid changes and some general TLC and it should be good to go. It has a sad story attached regarding the owner and has sat since Feb/March, having been run only a few times for any length of time. It was only run once a week or so before then. They were asking just under $2,000 before today. As is I'm thinking about $6 to $800 at most. Am I out of line here? That might save them some additional trouble.
Also, it shows a wet weight of just 50+/- lbs. over my ST1100 (which is supposed to be a top heavy bike) - it sure feels a LOT heavier than that! lol! Just an observation!
