Those 90-95 models have a problem with the balanced drive chain. The manual suggests adjusting the chain tension every 7500 miles. Adjustment requires removing the right side engine case cover (and scraping the dam# Suzuki gasket!). Most owners never bothered with this maintenance so most 90-95 bikes have balancer drive problems. Many of the parts required to fix them are no longer available. Good used balancer parts are pretty much non-existent.
The whole system was problematic and Suzuki redesigned it at least once in the model's short lifespan. IMO, if you did find a good one you should plan on adjusting the balancer chain more often than the manual recommends - maybe at every oil change.
Thanks ProCycle. I have pretty much ruled it out...I don't want to make a hasty purchase out of desperation. I am kinda dead-set on an electric start bike, and 24 years old is getting pretty long in the tooth, even if it has been cared for and rarely ridden.
