Need help with YBR 125 MOT Prep

[eNtak]

Okay so I have recently brought a Yamaha YBR 125, I have worked on bikes before and riden dirt bikes so I am not a complete noobie

Here is my main question but please read the rest. Will having no chain tensioner/Pullers/adjusters cause a fail on my MOT?

Upon getting the bike I decided to strip it and make sure everything was serviced, well maintained and clean. Upon removal of the the chain (which was horrid, grimy, gunkey...etc) I noticed that the chain adjusters/pulls are the rear of the swing arm was only holding on by say 3 threads. I loosened the threads and noticed that the chain was still really tight, no slack, nothing.

I later found out that the bike has a YBR CUSTOM modelled swing arm, not the standard YBR. My guess is the previous owner install it second hand because it was cheaper.

So I have a couple of options #1 Buy and new swing are for around £40-£50.
#2 Buy a longer chain and sprockets which are around £30. #4 Add links from a different chain or buy extra links and fit them.

The final idea #4 Drill and file the wheel axle hols so they become longer allowing the wheel to sit closer to the frame which was the cheapest and quickest option costing me nothing but some labour and allowing the chain to have the correct slack.

This is what I have opted for. Now my problem is the chain adjuster/pullers are not long enough and don't seem to be able to find any that are longer than stock which are below

Can anyone help ?

bet option #1 is looking good now!

I think making them longer would be my choice.

I doubt you will find an off the shelf alternative imho

Skim reading and searching key phrases and I didn't notice anything in regards to those adjusters, I would be willing to gamble it's not a failure, but I'm no expert in such things.
Depends if you CBA to scrutinize everything on the list, for it is long, and I am lazy.

Not sure if you've riveted a chain before, but to lengthen it you're going to need a tool to do so.
The ones I've used for <£50 fell apart on first use too, but that was for big bike chains.

Afterthought:
If you want the temporary illusion that the tension adjusters are present and working...
In theory you could just hacksaw some piece of bolt the same size as the adjusters, and chemical metal them to the end of the adjusters in situ then chuck the nuts over to hide any joins.

It's BodgyGuard as fuck, but they literally serve no purpose once the wheel is clamped so meh.

Permanent solution you could drill and cut out the adjuster bolts you have, and helicoil or chemical metal in some longer bolts.
Usually here people recommend you professionally weld the new bolt in to 4thou, but I don't even have a garage let alone a damn welder.
