Motor never made noise like this before. The bearing was wasted but not that bad(copper but not torn up) and crank was fine as well as the clearance with new bearings. It just barely started making noise and was shut down.

The noise is deffinitly coming from the top end. I looked close at the valve adjuster ends and they are pretty worn. They should probly be changed but I dont think that is the noise. They are original an have 140k of hard miles on them.

There was almost no signs of metal in the motor before when the bearing went bad. I split before the old and new filter to check. I had removed the valve cover before tearing into this to check for metal and found none.

Before when I started hearing the rod knock it was only if it was reved and decelled. Its a totally different noise now. Deffinitly not a rod knock. Oh and if it was a rod knock it wouldnt be getting quieter the more it runs. It now will actually come and go. I let it run tonight and it went away for awhile then came back but not as loud then went away again.

Oh yeah it a 9422re with a dual chain metal backed guide setup in it. The rest has been made stock again awhile ago.
