1986 gsxr750 problems
 

I have a ticking sound coming from my engine all the time. I took it in and the mechanic said i have a problem with the bearings and the engine will probably give out soon. I just recently purchased the bike and the motor was rebuilt and has 1000 miles on it. I was hoping someone could tell me where i can get either another motor for it (around the same year) or where i can get a rebuild kit?
