bought a 1999 Zx9r early March(just before quarantine)for 1000$(from a guy Big C).He claimed the carbs were cleaned even tho you could tell the bike was stored inside for a while. However he started it up,sounded beautiful. Go to rev it it dies..the throttle was reversed. —Fast forward to now— I removed the carbs from the bike,got them cleaned+jets replaced (still sputtering 1st all the way up) changed spark plugs. I’ve looked into the gas tank and either the liner has gone to plastic bits or this guy spilled paint in the tank.I’ve cleaned the petcock out any answers on how to dissolve paint liner? Long list...
