Exhaust WOF testing. Failed.

**Morcs** · 22nd October 2009, 17:54

Apparently the can on my NC35 is too loud.

Its loud, but not outrageously loud. Its quiet compared to my Fazer, and a lot quieter than big twins like Tls and VTRs...

I tried getting a warrant at cycletreads as they know bikes, and will know whats important and whats beurocratic shit, but wasnt happy with the exhaust test.

Whats the manner in how its done? Im pretty sure it was done in the workshop. In a building. WTF. sound reverberates and is amplified?

Anyone know somewhere I can get a warrant?

If I pay for a warrant, I expect a warrant.

There used to be a recognised international standard they could use to determine exhaust noise.

But they replaced that with a shit knee jerk law to the "Boi Racers"

get my warrant done at ross taylor auto in pukekohe. Rode bike in........skidded to prove it had brakes. turned it off. They checked lights and mirrors and tyres, didn't start it or take it off the stand.
2 minutes.
warrant done.

I got my wof done yesterday, at a car garage. Checked lights etc, pivoted bike on sidestand for wheel bearings front & rear. Cursory check of the brakes. Jobs a goodun. But I have indecently loud pipes & it never gets mentioned. I would suggest a local car garage, they have fewer facilitys to check a bike & seem to rush them through as if they are to much hassle. How does an open piped Harley get a warrant?
I was in cycletreads a while back for tyres & a Harley came up the ramp, I nearly shoited meself!

They have an Info sheet in their VIRM that tells them the test procedure and how to do it,what instruments are authorised.Noise is not quite what it sounds like.The limit for a bike is 100db,but unfortunately they have to fail you at 97db to allow for discrepancies.So then you have to supply proof that it is under 100db.

Get your arse into gear and get it quiet.

Go to VTNZ parnell - The Strand. I took my MV F4 1000 with a race system (LOUD) & a 996SPS (NOT QUITE MV LOUD) with a termi race system - no drama's. passed 1st time in.

you will have to wait the 28days to go else wear as it will be loaded on to the system.......
I took the CB250rs with its new system and they didn't even test the noise leave which susprised me as it sounds more like an old british

dont worry

Hibiscus Coast Batteries Tyres & WOF Centre
15 Arklow Lane. Got my warrent there today. It truely took more time filling out the paper work then testing the bike. $25 and they do it outside and don't even bother hearing the bike running. Or the place next to the caltex on Kihekatia flats road in dairy flat, my old man takes his Guzzi with harley fish tail pipes (rowdy as hell) and the dude just prefers to talk about the bike while he puts a new sticker on it.

You mean regardless of whether it meets the regulations or not?

Yea I thought the same thing -what you pay for is the TEST pass or fail is up to the tester

Morcs -there are actually 2 soundmeter tests but I wont go into that bit.
The important bit is that the noise test must be done in a specific way.
OUTSIDE--defined as an open area with no noise reflectve surfaces and
With background noise not exceeding a certain noise level.The meter must be set up at a set distance and angle from the exhaust.
One silly bit is that although MNZ specify an RPM the noise is tested at the LTSA dont.

Thats one of the pointless things about this whole exhaust noise level thing, as you can put your stock cans on for the wof, get home and put the nice ones back on! they may as well not bother eh.

Good to know. Cheers for that.

Within reason. I like it when issues are raised that I didnt find myself.
If its safe to ride, yes, I expect a warrant.

Ive found a place that will pass it too

Correct. My boy's car failed on mods at one testing station and when it was pointed out that the mods were certified they wouldn't accept that they had missed the cert and still failed it. He drove to the next testing station and got the warrant - they didn't even pick up the mods or check the cert mind you.
