I just installed my wiseco pistons and eagle rods. I started the motor for the first time and it started fine and ran good, but there is a knocking noise now coming from the motor. I rechecked all of the valve lash and everything was as it should be.

Any ideas what it may be? I am running honda green rod bearings.

Thanks,
Craig

Could possibly be a spun rod bearing. I'd definately pull the pan off, and check everything before running the engine any more.

maybe rod bearing if it knocks pretty loud, dont run it anymore or you will risk damage to your rods and crankshaft. i had no idea what it was when it happened to mine, i thought it was my valves getting jacked up, snap, motor wouldnt start, 2nd rod bearing spun and shredded nice thin layers of metal sheets! yeah, like he said, check your oil pan, or actually your oil should smell a little different. if so, your in trouble.
