Well the MOG in at Richard Thorne big banging noise from rear when pulling away with gusto! Ok normally, thought might be belt but there mech says it's all tight! So he dropped oil out of BB all nice n clean no bits of metal or out else. So left it with them we wait for phone call☹️ You too? Hopefully they will solve yours then fix mine in a few weeks when it goes in for its annual!!!

Having reached the point where the noises have been minimized but not entirely removed. Am now at the place where if I don't hear something anymore then it either failed completely or is laying on the road somewhere behind me.
As for the original poster I would add that it could very well be the belt ratcheting, hopping a tooth, while lighting out quickly. I had this happen to me a few times in the early days but I have since stopped it as the belt runs on the looser side as well as the practice eats the rear tire quickly!
Punching it to make a point or win a quick scratch race is all well and good but I have gone through three rear tires and five sets of fronts due to hard aggressive driving. It gets expensive. How many miles on your car at this point?

Over 32,000. A lot of experience behind that number.
What's your mileage? Who cares. Is it practical? See #1. What happens when it rains? You get wet.

Has the noise gone? Of course, if the BB is being re-engineered per the other post then you might not care about the longevity of the current unit's bearings. On the other hand I suspect tightening the belt was easier than Phil's solution...
