Pictures fixed 
Could be completely wrong but it looks to me like it might push out rather than unscrew, but could be rust seized so will require a lot of force.
I've never actually removed the linkage on one of these bikes so I wouldn't start hammering until someone else can confirm though 
@bakerDT125R-SM I ended up selling this middle of last year and forgot to update the thread!
Never heard of this MOT rule before 
I'm assuming a hand made pipe would fail too then unless the creator stamped some numbers on it?
I imagine the sound you heard was like the first few seconds of this vid?
In that bike's case it was the bottom end on the way out and there was play in the conrod but obviously shouldn't be the case with your bike.
Could be compression related though I guess.. Did you get your cylinder checked for correct sized piston?
It's a Grom with a KTM LC2 engine (Same as DT engine)
A chap named Mike Taylor is building it. Pretty cool I thought. I found riding an actual Grom pretty dull so a DT engine might make it a bit more interesting.
Just to chime something else in, my TDR doesn't really have much past 9-10k either, but it seems to be due to a small hole where my silencer meets the expansion chamber. Whenever I patch it up, I get much more pull up the top of the rev range. Sadly my fixes don't last long 
Would you consider moving the forum to a faster machine altogether? Maybe a VPS?
Vultr.com $2.50 per month for a decent enough Linux server. I'm sure a few of us on here would be happy to donate a few quid to help the cause
Think most places charge now. Surrey and Horsham do and there's lots of lanes for the opportunists in these areas.
You probably will do yes, clutch baskets can break pretty easily without the proper tools. I know from experience..
Anybody else go to Hastings today?
Haven't been on Mayday before, it was mad!
Never seen one of these before. RSK 500
I owned a DR-Z 400S for around a full year before my top end started rattling.
However, it only happened because it drank oil without me realising.. So considering I only topped it up after noticing the knocking, I would say it lasted well :face_with_tears_of_joy:
Overall though I found mine way too heavy. Sold it for a WR 250F which I was way more suited for.
