As to not to high jack a thread, back in '09 I was having bearing issues. I was running .0025/.003 clearance turning 7500 RPM with an Eagle crank. I found that the crank was bent and replaced it with a Compstar. I was also told my clearances were to tight and I was told to use .003/.0035. They ended up at .0029/.0034. Now lately I've been reading and it seems my clearances are big and it's being recommended to use the tighter ones again. I've checked my bearings and feel I can reuse them and only replace the rings. Now I'm wondering about clearances again.
