Just bought a 91 Kawisaki KDX200 and took the water pump cover off to inspect, and a big surprise, the impeller falls out along with the impeller bolt head, with the remaining bolt lodged inside the gear shaft. Who knows how long this has been running without any circulating water. Luckily I've only used it once since I bought it.
My question is, how does something like that happen? My brother says bad bearings but they seem fine when I took the engine cover off to remove the impeller gear shaft. My guess was someone left water in it for the winter and tried to startwith frozen water in the impeller housing and just snapped it off...any ideas?
