Important mot update

[craigT19]

Hey guys just thought i would let u know that as of now mot 'ers' have been instructed to ignore bs kite marks on exhaust pipes.

It is now at the testers descretion to fail u if he "belives" your bike to be louder than stock.

This is to crack down on fake bs tags and road legal cans with the baffles removed etc.

Within the next 4 weeks we have been told to expect a new noise tester in dB's along with a list of bike modules etc... if it reads more than 5 db's over what the manufacturer claims at 7k rpm we have to fail it.

You have been warned

I take it you are given a suitably damped and soundproofed room to test in? Echoes from a confined space will ramp up the dBA level on a can rather a lot. If it's just done in the yard, or even worse in the workshop, you'll be getting rather high readings.

Two problems though.

What if an untouched manufacturers can fails?
What if you can't get information from the manufacturer about how loud it is supposed to be?

Thanks for the update though.

no idea mate, the sound tool fits over the end of the can, so echos shouldnt be a problem.

All cans are tested b4 put on bikes so failiure shouldnt be a problem... i think the 5db over rule is there due to possible baffle wear ect but if it does fail then its illegal anyways, in warrenty...then its a manufactuing issue.

out of warrenty? better get on ebay

I just see potential fun trying to get any sort of meaningful noise emissions data out of the Hongdou Motor Corporation for my bike, ignoring the fact that it's far too loud for a normal 125 single.

Ditto with the MZ. It's the damn loudest 125 4t I've ever heard. Not as loud as when I get the race can though

Which is why I think, for bikes used on the road, exhausts with removeable baffles are a sensible purchase.

[numark1]

Looks like i'll have to slip the "normal can" on for the test then.

Cheers for the heads up.

My MOT guy is nearly deaf He used to race classic bikes with almost open pipes on them, so he isnt going to fail mine. Which is good cos theres nothing like a kite mark on my new silencer.

I have E Marks and BSAU Marks on my twin Jama exhausts.

So what happens in the case if you have twins then?

[mattsmith95]

My mechanic was telling me that when he MOT's a bike it's down to the sound of the pipes.



BTW, The price of an MOT is due to rise to £26 soon.

Tie a shoe lace around a sponge and shove it down the end of the exhaust. It might not run too well nor sound too pretty but it should get it through the test and is easy to remove after

[Dam_buster]

until the mechanic calls u and tells u a sponge just shot out the exhaust and hit him in the face Lmao!

Looks like we are back to shoving scouring pads up the exhaust for the MOT then

Interesting factoid. If you take the end off a race can that is held together with allen bolts, a coke tin slides up in there nicely. On a bigger bike, a couple of miles sees said tin shredded to bits and spat out. Used to be quite a common dodge to get track day bikes through scruitineering with a rediculously loud exhaust on tracks with a noise limit.

Jeeze, take it easy dude. So maybe he got it wrong, we all make a mistake now and then, no need to destroy the bloke.

You can resolve all this bollox by getting to know the lads down the garage.
My huge can sailed through.

CBRnick, who put a bug up your ass? A simple, 'sorry mate, but actually you've got things a bit wrong. It's...' would suffice - not:

[R4nger]

And your being friendly?

[CBRnick]

Sorry.
It just gets up my nose when people post 'information' that could land people in trouble or with a large bill.

Would you want to have your car or bike tested by an MOT station that is using out of date rules, testers who dont have a clue what they are talking about and illegal Db tests ?

If you do fair enough. I dont.

Personaly Id see them out of business and in court today.
I cant do that though so Ill trash people who post incorrect, misleading and plain wrong informationwhich could result in someone elses misfortune in the cause of getting as little business to them as possible.

[craigT19]

<edited> cant be bothered to argue..

just trying to let poeple know that after market road legal cans / stock cans etc will now fail regardless of bs marks if the baffles are out etc


appologies for the rant guys, just been a nasty day trying a assemble a new addition to yamahas 125 range without an instruction book of any kind
