2001Stroker Posted April 15, 2008 Report Share Posted April 15, 2008 A knock could be a number of things. I heard, and still hear a knock from my fresh 421. It has about 5 hours on it now. I started freaking out when it started. Are you sure it is coming from the lower end. I thought mine was too, until I put a stethoscope on it. Mine was coming from the intake. Not the carbs or the reeds, but the intake. My intake has a crossover tube in it. I don't know if it is just noise within the crossover tube, but it is annoying. I just ignore it. Put a stethoscope on it, and find exactly where it's coming from. If you don't have one, just use a long 3/8" socket extension. Put your ear up to the ratchet end of it, and touch the socket end to different parts of the engine while it's running. You should be able to hear it good like that.

Banshee_Bandit Posted April 18, 2008 Author Report Share Posted April 18, 2008 Well today had enough time before I got to work and took off the pipes as well as the Reeds to see if my pistons had any signs on them... Both sides seem to be in very good condition no signs on`em ...so my mixture had to be correct i suppose, them plugs says it either... took the advice with the 3/4 extension and heard all around the engine itself... it seems the knocking come soemwhere behing den Clutch.... so what might that be, I mean the engine runs very well only this anoying kocking sound.... Any help would be appreciated !!! Quote Link to comment Share on other sites More sharing options...
dajogejr Posted April 18, 2008 Report Share Posted April 18, 2008 Our friend had a similar sound. Ended up having a shattered clutch plates. For the cost of a gasket and tranny fluid, that's where I'd start. Quote Link to comment Share on other sites More sharing options...
