    Vehicle noise tests - New rules

    Well LTNZ are finally coming down on the boy racers.

    Unfortunately the new rules also apply to motorbikes.

    Hands up all those people with modified exhausts.

    I guess we'll wait and see how this affects us. Enforced wef 01 June 2008.

    Just keep your old pipes, I believe it is quite quick to swap a MC exhaust around. So every 6 months and it shouldn't be too much of a hassle...

    i think we'll be alright guys as the noise testing is only done on imported vechicles after the bill is passed not bikes that are currently registered.there will be know added noise test in the WOF only the usual visual check on smoke

    Do you realise how many holes there could be if people would just take the time to take the dirt out of them?

    I wonder how many currently authorised WOF service suppliers will leap out and purchase a correctly certified sound metre...

    Cool

    In Scandinavian countries this has been in place for years. What the result is that you have different WOF pipes. Then after successful WOF you swap them. On the road the police stops you and tells you that the pipes are too loud. You disagree. They give you a ticket stating that you have to get a new WOF. So you ride home, swap pipes and you have your new WOF. Normally happens 2 - 5 times a year. A pain but part of reality.

    May the bridges I burn light the way.

    Easy to blame the boy-racers but there is a shit load of Harleys running around Christchurch with open drag pipes that a f-n loud.

    Re Harleys and loud pipes - a deep mellow tone sounds good to my ear - a HD with open pipes sounds like a untuned piece of shite. I get the feeling it is - if its REALLY loud it must be fast - look at me go!

    Before some weaner gets upset at HD bashing - consider this - I work in town and see & hear all the bikes up and down Manchester St (bike shop strip here) plus live on the main route to Akaroa which means I get to see and hear heaps of bikes every weekend (dam shame) so I am in a good position to judge who is the loudest group/brand. Suck-on-that.

    I see my new Hornet has a sticker saying at 4500rpms it is rated at 85db. My GS1200ss had a full Yoshi system rated at 94db - man that 9db is a lot of difference! About 90 would be sweet.

    I see if registered prior to date gives a higher rating - in theory I can make the Hornet a bit louder and be legal.

    You will also note that mopdern slip on pipes coome with a db killer stuffed in the end - I'd say 90% are removed for street use as the new $700 can does not sound much different from the stocker!

    Expect to see these db killers welded in and non removable in the future.

    where opinion holds more weight than fact.

    It's better to not pass and know that you could have than to pass and find out that you can't. Wait for the straight.

    None. The objective noise test must be done by a LVV certifier approved for that purpose. Normal WoF places can't do it.

    There are a grand total of two (yep, two) such certifiers for the Auckland district. Expect lonnnnngggggg wait times!

    Ah, grand scheme.

    Seems I recall that practical considerations involving the scarcity of such equipment was the reason they demured last time the topic got all political.

    Glad to see they've cleared that up, I so enjoy seeing concise, accurately targeted and readily applied laws enacted.

    Must try to be less sarchastic...

    I had a bike "failed" because I had non-factory pipes on it that were "obviously louder then the originals". I said to him they were under the legal limit, and his reply was that they dont test it with a sound pressure level meter (he didnt use those words, I used those words now because thats what it is really called). I was told their rule book says any non-stock pipes are an instant fail. This was at AA in Hornby.

    Fuck them.

    I took the bike then and there to a WOF place reccomended to my be a bike shop, which happens to be accross the street from the bike shop. Passed, with just a note I should be considering new tires soon.

    AlanB can untwist as well.

    He's right, though; there are some excessively loud Harleys (almost always Harleys, very rarely is it another type of cruiser) which have completely open pipes. It's not a tone, or note, or anything; it's just a horrible loud blare, like a huge diesel truck with a shagged-out exhaust system. Not pleasant at all. I don't mind loud bikes, there's a Suzuki C90 near my work which is also fairly loud, but it's a shaped sound with a note, not just a rackety blare. What I loved the most though (even though it made my ears bleed) was the DBD34 I sat behind going over the Harbour Bridge

    The other bad ones are the Subaru cages, with the boxer engines, which can make a nice V-twin-esque thump, but sometimes are just too unbaffled and instead just throb until you want to throw up.

    Noise polution

    You don't have to be Einstein to work out that the idiots riding Harley's with straight pipes, have fucked it up for everyone.

    When will these no brainers wake up. First thing they do when they buy a new piece of shit Harley, is to put a fukn great drill up the pipes. So now they have this shimmering, shaking, jack hammer, piece of gutless, shiney, shit roaring it's heads of, the fact still remains that they are a gutless heap of shit, that wouldn't pull a soldier of your sister.

    OK, now that they have pissed everyone of, with the racket they make. The law makers are bringing in new laws that fuck it for everyone.

    Harley owners want shooting with a ball of their own shit. IMO
    grrrrrrrrr!!
