What else was an issue? My 89 first bike was rock solid, especially being a newly minted street rider...
I'm sure a decent version of that bike would be fine, mine was a train wreck though.
It's been a while, but the main issue was the gas tank was completely rotted. Didn't know much back then (then?) so I paid someone to clean the carbs when they got full of rust. Then it happened again after a few hundred km's, so the guy cleaned them again and installed an inline fuel filter, and gave me a few spares. About every 100km's the fuel filter would get clogged up with rust and the bike would sputter. Once it started sputtering/stalling, pull over, lift the tank, swap the filter. Rinse and repeat.
Over the winter, I tried cleaning out the tank with acid, metal was so thin that I ended up with a pinhole leak. Noticed the drip on the first ride after, not a comfortable ride to get it home. Top tip, JB Weld works to seal a gas tank...
Besides that, the seat was poorly recovered causing it to absorb water when it rained. Plastic trim was all half broken. Gauges weren't original (found out after purchase) so who knows what the actual mileage was.
Sold it quickly after the gas tank incident and bought a near new FZ6 that was bulletproof.
