Re: Advice on buying a used vulcan 750
Unless the gas was drained before it was stored, the fuel system is probably gummed up. That leads to stuck floats. Since there's two carburetors, one could be working well enough to get the bike running, the float in the other could be stuck. That'll cause rough running and gas flooding the unlucky cylinder. That usually means pulling the carbs for a thorough cleaning if things are really bad. Sometimes a couple of doses of SeaFoam will clean them out. Anyway, it means something you're going to have to take care of before it's ridable. The oil's probably never been changed nor the battery. So if it starts, they probably just charged up the battery. The other big bugaboo is the stator. I'm not sure if a '94 got the crummy stators or not. At some point in time, Kaw switched to a cheaper, far less durable stator as a cost cutting measure. Anyway, that would have to be confirmed good before putting any money down. A quick test requires removing the seat. Using a digital voltmeter read the voltage across the battery at 2500 rpm. It should be at least 13.5 volts. Any less and the value of the bike just dropped to about a grand. If the first voltage check is ok, rev it up to 5000 rpm. The voltage should be lower than 14.8. If it's higher, that means trouble too. Replacing the stator means pulling the engine and it costs about $800. Most bikes don't have a problem, but mine (an '04) had a bad stator right off the showroom floor! So you can't assume just because it has low miles, that critical item is ok. I'd say $3000 is way too high a price for such an old machine.
