This is an 06 r1 engine. I had a noise that sounded like the common cam chain tensioner, but after installing the APE tensioner it seemed like it went away for a bit. Then it came back, so i just did a whole engine swap. After opening this engine, I see these scrapes on the side. Is it a spun bearing? Am I able to just replace the bearing and it be fine or is the damage to the crank too far gone?
Thanks
