My 400/4 seems to have developed this knocking at tickover. I was just about to try and adjust the cam chain, following some instructions I'd read about removing the bolt above the cam chain tensioner bolt and pushing a screw driver in to do the work of the springs, and I couldn't remove it. My socket extension wasn't long enough so I need to get a longer one if I'm going to do that.
Anyway, before doing that I convinced myself the noise wasn't the cam chain. It seems to come from that area under the carburettors. I just wondered whether anyone had any ideas what might be causing it and whether it needs a major overhaul. Here's a link to a recording I made https://youtu.be/ENf3vm9v_BE
