MOT test, chain loose advisory, but chain fully enclosed

[MarkJ]

Hi, twisted subframe jokes aside, I left my bike at an MOT station to be tested and supposedly I have an advisory for a loose chain. My issue with this is the bike is a CG125 with a fully enclosed chain, and yet it supposedly has an advisory for a loose chain. I've had an advisory for this in the past when the chain was loose and you could hear it touching the inside of the chain guard which was fair enough. However I tightened it this time to avoid this advisory (and tested to make sure it wasn't rubbing the guard) and yet I apparently still have one for it.

There is a rubber bung on the chain enclosure you can pop off to test chain slack, but I thought MOT testers couldn't remove anything from the bike? Anyone had this before?

if you have a new mot certificate with an advisory on it(there is nothing supposed about it) then the tester thinks that it needs adjustment or will need adjustment soon,
however as its an advisory it is entirely up to you what you do with this information.
you could spend a couple of minutes adjusting your chain correctly.
or you could become the next jivebunny,
its your chain.

I reckon they invent some advisories every now and then. I've had 'rear pads low' before when the pads were new...

This what the tester's manual actually says:

Scope of Examination

The MOT Test does not allow for any stripping or dismantling, except for the removal of panels or covers, designed to be easily removed without the use of tools, where it is necessary to allow the examination of an item. Panels and covers must be securely replaced at the end of the test.


So, you can remove access panels and rubber bungs, providing you don't need tools to do it and you can reasonably expect to do it without damaging anything.

Chain tension is a testable item, the rubber bung is there to allow you to examine the chain, therefore it's perfectly proper that a tester would remove it to check.

Advice. Adjust the chain 'properly'.

It's not a big job FFS.

You should be embarrassed to get an advisory for that. It's an Own Goal really.

Adjust it to it's tightest point by checking slack when the wheel is as several positions.

And get on with your life as a biker.

Cheers shaft, I always thought they couldn't touch anything, didn't realise things like this were allowed

I wasn't bothered about the advisory, just that they'd undone something when not allowed. Chain is fine, I always have them on the loose side - sympathetic to output bearings.
