Warning re exhaust systems.

[Motu]

I put the new regs into the VIRM last week.....the shit is going to hit the fan boys.I don't think it'll be safe for me to ride my pushbike to work anymore.

I just read a pamphlet from the LTSA and it said motorcycles had to have a sound rating below 97db as of June this year. June's in a few days...

100db - but it says 97db in the VIRM as they have to be the same or less than the OE system.So careful with that one - if they fail you at 99db it's still legal.

Your right... and all at the whim of a WOF tester who can throw you out because he/she feels like it and then you have to pay upwards of $200 (est) to a LVVTA tester, or spend the money first and get stickered.

We shall see how it is greeted and used eh.

I wonder how we'll get on with our aussie spec K6 GSX-R750s that have a noise label on the frame saying 102dB?

[McJim]

Can we clarify that the official decibel measurement is supposed to be at 1/3 revs? Is this true?

I thought that the measurment was taken at 3,000rpm where redline is 9,000rpm or at 5,000rpm for a 15,000rpm engine.

I don't want anyone revving the snot out of my wee bike at a Warrant of fitness test.

Or simply go to a different station for another opinion? (That opinion might cost you the cost of another WOF inspection though).

[nallac]

shit i measured my mates RX3 coupe rally/road car the other day
i was standing about 4 meters away it measured 97decibals at idle.
went up to105 as he drove it up on to the trailer.
probably only took it up to 3000revs max.

its handy when ya know the WOF inspector..

[ManDownUnder]

Why, is it loud polishing those bikes? HAHAHAHA!!!!!! I think the regs are when they are turned on!!!!

[insane1]

oh bugger there goes puting a full yoshi system on the burger damm i was looking forward to it too.

[AllanB]

99-100db limit on motorcycles?

Are you serious - that's way too loud.

Fark me my GS1200ss with the full Yoshi was rated at 94 db and I considered that loud - often too loud. 100 is farkin loud.
