After I had been riding my 300 around I put it in neutral and noticed a pretty loud clicking noise coming from the left case of the engine, where the stator and starter gears are located. The bike only does it when it is in neutral and once I go into drive it is fine. Any ideas? It doesn’t seem to be causing any problems because the bike runs and drives perfect its just annoying to have a completely rebuilt engine making noise. **I did not rebuild the engine and am wondering if they put it together wrong.
