I have two counterbalance shafts both were removed from 1995 Thundercat 900 they are being sold separately. They are sold as a core not working shown in the picture. The one in front, the bearing behind water pump is rough other three bearings spin very smoothly. The one in the back all four bearings spin smoothly.
This is a multiple listing. There is corrosion on the shaft where water pump seal rides.
