just to answer your question lx5liter, it only knocks during deceleration. I actually pulled the motor the other day and removed the crank. All of the rod bearings are fine, but it looks like the #1 and #5 main bearings are worn and the crank itself has some marks. The motor only has about a half hour of drive time.im gonna plastigauge it to check the clearances this weekend. but the only explanation i can come up with is that they were bad bearings or a bad crank. the whole motor was freshly assembled with almost all new parts. Im getting really frustrated. I want to hit the streets
