Exhaust WOF testing. Failed.

[Rodney007]

bro, your rvf is too loud but so is every sports bike with a muffler..

fu*k the 28 day thing, I failed at one place, passed at another 20 mins later... just goto where I said and youl pass, providing the rest of the bikes legit so tighten up your steering head and foot peg and youl be all good!

[Morcs]

ah, so your son is a boy racer? does he take after his father in his avasion of the law?

Mate, pm us your address, get some beers in the fridge, and we'll drop by one thursday night and have a yarn. Youll see we are actually a bunch of good coonts.

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.

go to AA in glenn innes for a wof. They will use a torch to inspect the frame and test the brakes and indicators and lights. Thats bout it.

The bastard who tests the bikes though like to test the brakes by riding the bike around the center, he jumped on ma 250 a couple months ago when I was getting a wof and tested the brakes. If he tried that on my bird, he will get a swift kick up the arse.

get my warrant done at ......... 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.

Great mate! You've just painted a big target on their back. Now everybody knows (chances are, including the authorities) that they are giving WOFs too easy. Too bad you haven't posted their address too

And that's how things like this don't last. It's enough to pass one loud-mouth and all the town knows you are giving WOFs too easy (including the police) and before long you get in trouble.

[ital916]

Sorry WRONG you can go somewhere else right away



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.

I hope they know how to use those sound level meters. Results will vary depending on whether a slow or fast response time is used, what the operational octave band and frequency range settings are. Whether it is swtiched to RMS and so on....bloody nuisance, sound level meters...and dB are a crock of shit, completey archaic and confusing as there are three different interpretations of dB.

Well the original poster should edit their name out, and you should edit the name out of the quote.

As per the LVVTA standard 90-20(02)

Test site requirements
2.2(1) A test site used in the application of this standard must be an open outdoor site that:
(a) is predominantly flat, particularly within the immediate test area; and
(b) incorporates within a radius of not less than 3 metres (10 feet) from the sound level meter microphone:
(i) a space free from large sound-reflecting surfaces including buildings, walls, billboards, vehicles, trees, or shrubs; and
(ii) a solid surface such as concrete or asphalt, free of any loose or sound-absorbing material.

2.2(2)
Exhaust noise emission testing on a low volume vehicle may be carried out under a canopy, provided that no part of the canopy, including its supports, are within 3 metres (10 feet) of the sound level meter microphone.

Motorcycle engines
2.6(2)
The engine speed for the exhaust noise emission test of a motorcycle engine, must, for the duration of each test, be within a tolerance of +/- 5% of either:
(a) in the case of an engine that has a manufacturer’s engine speed maximum power (ESMP) that is known to the LVV certifier, 50% of that figure; or
(b) in the case of an engine that does not have a manufacturer’s ESMP that is known to the LVV certifier, or the manufacturer’s ESMP has become irrelevant because the engine is now outside of its original specification:
(i) 6000 RPM if the engine is a 2-stroke single-cylinder engine; or
(ii) 5000 RPM if the engine is a 2-stroke multi-cylinder engine; or
(iii) 3000 RPM if the engine is a 4-stroke single-cylinder engine; or
(iv) 2500 RPM if the engine is a 4-stroke twin-cylinder engine with 2 valves per cylinder; or
(v) 4000 RPM if the engine is a 4-stroke twin-cylinder engine with 3 or more valves per cylinder; or
(vi) 4500 RPM if the engine is a 4-stroke engine that has three or more cylinders;
or
(c) in the case where a low volume vehicle certifier believes the engine speeds specified in 2.6 (2)(b) are unreasonably high,
taking into account the type and age of the engine, he may apply an engine speed for the purpose of the sound level test at which he believes is appropriate for the engine, and at which the engine may be safely operated.

(a) in the case of a moped, 91 dBA; or
(b) in the case of a motorcycle with an engine capacity of 125 cc or less, 96 dBA; or
(c) in the case of a motorcycle with an engine capacity of more than 125 cc, 100 dBA; or
(d) in the case of an MA, MB, MC, MD1, MD2, or NA-class production vehicle that was manufactured before 1 January 1985, 95 dBA; or
(e) in the case of a scratch-built low volume vehicle of scratch-built sub-category ‘Historic Replica’, or scratch-built sub-category ‘Reproduction’ that is a replication or reproduction of a vehicle manufactured before 1 January 1985, 95 dBA; or
(f) in the case of an MA, MB, MC, MD1, MD2, or NA-class production vehicle that was manufactured on or after 1 January 1985:
(i) if first registered in New Zealand before 1 June 2008, 95 dBA; or
(ii) if first registered in New Zealand on or after 1 June 2008, 90 dBA.

woah busting out the big guns

[Gubb]

Go to VTNZ

Ahahahahahahahahahahahaha!

You just rocked my world.

[popa griffin]

Roll up chiken mesh. spray paint black. stuff down can....

Go back get warrent. Hope it doesnt blow out on the way or while there.

Go home pull out with some long plier type dohickies.

[Disco Dan]

Name and shame the shoddy places that give out dodgy WOF - we all have to use the roads !

If they dont pick up a simple noisy pipe then what else are they missing? I always take bikes/cars to VTNZ.

[bsasuper]

I have a loud can on one of my bikes. when its time for a warrant i simply bolt on the factory can, then change back, done

[FROSTY:Me]

Ya wanna explain that one to me please? If he ISN'T doing a brake test to ensure the bike stops then he aint doing his job.
