Don't think I've ever met a 60yo Snowflake!  You have stumbled upon a rare species! 

Here in the UK, we had no Covid buyout. Far from it. A lot of people lost their jobs and that was it. Some got fuloughed, others just kept going, like me 

Those two with the IPA were idiots. I suggest that the other 95% you don't know might be worth getting to know? We have a new batch of apprentices, and actually, there are some personalities, humour and friends to be made 

You did check the big end didn't you?

Hoping I am utterly wrong and the chain was banging to be let out.

Hey, about that timing chain. Finished working it up in June and had to move and started a new job so it has actually sat unridden for several months now. It did make the drive from old place to new so I'm not sure where to go from after replacing the entire timing chain and tensioners.

The sound has not changed in intensity or speed. Remains exactly the same.

I've done more forum post digging and come to a few conclusions and possible next steps. First would be checking if my clutch is out of adjustment. The noise doesn't change when I pull it in but some riders have mentioned a similar noise from old weary clutches which i definitely have one of. Second would be bent pushrods, I would imagine a bent pushrod would send me some wild information in a compression test but it is totally possible a pushrod bent and wants to make a ton of noise. Third would be piston slap, I guess it's technically possible. There was no sign of this when I last opened it up, pistons moved smoothly on the rods, but maybe theyve frozen up between then and now. Fourth would be connecting rods; at the end of the day I don't want to do connecting rod bearings but I would much rather do that than timing chain again. I'm willing to pull those out and see what's happening before the rainy season starts here.

For anyone seeing this thread for the first time, the noise is on the right cylinder. I was convinced it was timing but not the case. I am susceptible to being told to open the conrods if someone had a convincing argument in favor of it.

Also have a much better video of replicating the noise if anyone wants to hear/see it in action. I my post on youtube and link here if there's not an easy way to upload a video to this site.

I don't know anything about them, I wouldn't know them if I walked by them .
Since the Covid era, we had a significant amount of people took the buyout in 2020 .
They were replaced by people that had no experience in aircraft maintenance, fresh out of school .
When I walk through the hangar at 5 AM, I don't know 95% of the people that work the night shift .
I couldn't say one way or another as to whether they are bikers or not, I'm the only one that rides airheads .
There is only one other BMW bike that I see and it's a late model bike .

Please tell me they are not bikers. Worse, they ride airheads 
If they don't get criminal charges and costs, they will definitely get civil.
