Noise at Kaitoke

[F5 Dave]

This in from Fish & it makes sense to post it here

Hi Guys it has come to the kart clubs attention that the bikes are well over the acceptable level of noise. This was raised at the AGM last night, one of the kart members had a DBA meter at the last meeting and it seems that the bikes are about 20 DBA noisier than the karts with bikes around the 100 DBA mark. As I have said in the past, if you have a noisy bike PLEASE PLEASE make an effort to make it quiet! There will be a noise meter in place over the next few meeting so we can sort the issue out. If you get approached by someone on a race day please see what you can do with your bike to make it quiet. If your bike is deemed to be over noisy you will be asked to remove it until it can be made quiet.


Just remember that Roy’s Hill in the Hawkes Bay has suspended bike racing at that track due to noise complaints lets not have it happen here?? You have been warned.

Lets not lose a great track!

If you have any question please get back to me by email or at the track.

I thought the loudest thing at the track was the rotax carts warming up in the pits.

I thought the loadest thing at the track was the rotax carts warming up in the pits.

Some of the new bikes are just crazy loud. People are running really small volume, cheap mufflers. They don't work.

I just bought one but I think it may only ever see one round while I get a good system made.
It was such cheap crap metal on the end caps that welding was a issue.
Once I have some clipons ill try get it running and see if its quiet enough to run.

Do you know what method they were using?

http://www.kartsport.org.nz/downloads/Manuals/Manual_2012_Web.pdf

section M4 is about noise testing and what we had to comply with when I was racing Karts

Some of the new bikes are just crazy loud....

:killingme:killingme:killingme:killingme Not just new bikes Rich.

Team GPR just purchased a noise meter (I've just got to check its calibration against my work unit) to help us keep an eye on all of our bikes (not just buckets).
We can bring it down to the next meeting and make it available...

But you are right the cheap pit bike mufflers are rubbish and everyone needs to make more of an effort to quieten things down.

I would have thought that all bikes need to conform to the NMZ noise limits (and the rest of the Technical rules for the class): (Noise - 10.6.3.1 Chapter_10 (http://www.mnz.co.nz/download/2012_MoMS_Chapter_10_Motorcycles_Technical.pdf))

Do you know what method they were using? http://www.kartsport.org.nz/downloads/Manuals/Manual_2012_Web.pdf section M4 is about noise testing and what we had to comply with when I was racing Karts
or given Wellington running under karts; conforming to their rules (kart sport); which are tighter (either method) as Kickaha provided (Page 157);
I've noted a couple of times in the past a mic hanging from the control tower line; especially leading up to the Kart nationals. not sure if this is what prompted the latest comments....

It not a right to expect to turn up and race.
If your machine doesn't meet the regs; you should do something about it beforehand, rather than waiting for someone to tell you too (if its loud in the shed then it will be loud on the track)..
If people are having issues on quietening their bikes down then ask. Plenty of people have managed to get their bikes quite, I'm sure people will be willing to help (especially to ensure that access to tracks are maintained).

Reving karts in pits... Mossy you are right they are fken loud... funny thing is every briefing they say there is an area to do this but its not enforced and its even in the rules G1.17. :brick:

[Kickaha]

I would have thought that all bikes need to conform to the NMZ noise limits

Only if they are MNZ permitted meetings, but it would make sense to do so for those that do meetings like the GP or BOB that are MNZ permitted anyway

[Grumph]

All the kart tracks will be operating under a resource consent from the local council - which may well be a lower limit than MNZ....

Time I think for you guys to ask what the conditions of use are.

[Yow Ling]

When we race at levels the car club send a noise guy down, if you are noisy in practice you get warned to fix it now, if you are noisy in R1 you maight be told to put it on the trailer. Nothing motivates riders more than enforcment.

I guess it is a form of cheating really, if you find you can make more power by using a noisy pipe and a quiet one costs power then it was really an ill gotten gain, same as having a quiet pipe and 168cc

[richban]

:killingme:killingme:killingme:killingme Not just new bikes Rich.

True that. I have put a plug in the end of mine to reduce the noise. Not ideal. New pipe on the way. I have just purchased a big fat old Yoshi qaud bike muffler I am hoping to adapt for the bucket.

Surely a good place to start for people is a 95db rated dirt bike muffler. There are plenty of bargains out there.

Quads up here that went on the track were well over the 100dB mark on the MNZ reader, hope youve made a small end cap!

[richban]

When I was playing with Megaphones I made this little shroud on the end of this monster. It was made a massive difference. Pity the pipe didn't work it looks cool.

Final version ended up with more holes and slots and yes it was welded on.

[richban]

Its not a quad!

[fi5hy]

Might be as easy as pointing you exhaust end cap at the ground or finding another exhaust can that works. As for the karts warming up in the pits we can't stop that but when they rev them full tit they have to take them to the top car park which they do.

[hmurphy]

Apparently it's only the cadet karts (the big ones, I don't even know if that's cadets haha) that have to warm them up at the top of the carpark. Everyone else can do what they like. That's what I was told by the clerk of the course last meeting.

[Kickaha]

Apparently it's only the cadet karts (the big ones, I don't even know if that's cadets haha)

Cadets are for the small kids, biggest are Open class (up to 250cc)if they run them, other wise it's KT100 classes, Rotax max and maybe KZ1/2

I have the same pipe. It's definitely a cheapy but compared to many, if not most of the pipes there, it's quiet.

[mossy1200]

Cool. I didnt want to spend alot as I might go 2t before the end of the year once I have a good set up handling wise.

[NSR143]

My support for those asking for quieter bikes PLEASE...

Do not faf about figuring which rule is this and what the karts do and local council guides and MNZ rules. Just get in the shed and F-ing well get on with fixing the problem.

see my general guide as outlined in my 'winter exhaust projects' post some time ago below.

----------------------------------------------

The best I would suggest is that if you can run your bike up and down a residential street without causing to much public trauma or aggravation you're probably about where you need to be. (on a Sunday morning at 11:15am subject to reasonable local conditions and excluding areas prone to church services, riots, gunship weapons discharge, days of national mourning etc)


------------------------------

Sort it out or lose it!

[jellywrestler]

some I phones have noise meters on them , while they may not be perfect at least they're something you can use to assess how noisy you are to start with and how progress is when you're quietening things down.
Bear in mind too the noise your bikes emit will be louder on an overcast day, by up to three DBs so err on the side of caution

[BMWST?]

i think its also the difference in the way bikes and karts run...the karts engine speeds are probably more consistent than the bikes ?.

[John_H]

When is the noise reading taken i.e. at idle or maximum revs and from what distance from the bike?

[White trash]

I have the same pipe. It's definitely a cheapy but compared to many, if not most of the pipes there, it's quiet.

Fuck off. It's loud as.

[John_H]

Fuck off. It's loud as.

Then you haven't heard it against everything else there. It's not nearly as loud as many buckets.

[speights_bud]

My advice is don't shrug this warning off! From recent experience with official noise testing at Roys hill we've learnt a few things the hard way and now we don't have a track to ride on anymore.

Riders, if commonsense says it sounds too loud then piss off home or fix it, simple as that. We had bikes turn up for OFFICIAL noise testing (with all the proper gear and expensive man to operate it all :facepalm:) and riders were simply justifying their noisy bikes by simply saying 'But my bikes not even as loud as his/her one'. Even when some club members offered and phoned around two weeks before offering to come modify & quieten exhausts etc for the test day for FREE nobody took up the offer. As a result only a few bikes were at a level where you could honestly think that yea these are a 'sensible' volume.

It really doesnt matter fek all what the noise meter's give as a reading it's just an expensive piece of paper, if it sounds noisy or is annoying to neighbors regardless of what the actual readings say etc you'll have issues.

Don't fuck it up coz we don't have anywhere to ride here anymore and we need your track too!

[koba]

Then you haven't heard it against everything else there. It's not nearly as loud as many buckets.

So it's quite likely too loud then...

Next bit is a general stream of thought on the issue, some of it's been covered but it does need reinforcement.

Noise meters are good because they are an objective measurement that can be used to settle a disagreement and/or enforce or comply with a set standard BUT I think we should all also keep in mind that we are only going to have problems when someone complains based on their subjective observations.

Avoiding the subjective observation, whoever's it is, that leads to a noise meter being pulled out is the best course of action.

I think is easy to go "shit, he thinks it's loud but I test it at 50db, that can't be a problem".
Flawed logic that; if someone thinks it's too loud they may be a softcock or whatever but ultimately someone thinking it's to loud is what leads to problems. It has been pointed out that HEAPS of buckets are too loud at Kaitoke so that means there really is a problem.

Fixing this NOW is really important, don't wait get onto it now. If there is a slightest bit of doubt muffle it more!

Also, for what it's worth I've found having a bike that is quieter than almost all others on the track has given me a fantastic on-track advantage, I've made heaps of sneaky passes when people have taken a loose, non-defensive line because they have expected to hear a bike behind them.

The next pipe will be even more muffled.


EDIT: Can you tell I didn't read the post above before posting? Still, It bears repeating...

The sneak attac, works a treat .....

Time I think for you guys to ask what the conditions of use are.

Correct. If the RC doenst cover you, no matter how little the amount of noise you make, if your not allowed to be there....it wont take much.

[hal20308]

Correct. If the RC doenst cover you, no matter how little the amount of noise you make, if your not allowed to be there....it wont take much.

I think we're all in agreement here: let's be proactive and be seen to be policing ourselves and it will go a long way to ensuring this issue does not get any worse. It's been raised at the kart clubs AGM therefore the committee will be under an obligation to report on it next time. So, if the dB meter is there on the next kart day let's start taking some readings from everyone's bike and recording them as a start. Let's also ask the kart club (as has been suggested) what the limit should be, but seeing as "too loud" is subjective, let's be flexible enough to come up with our own limit that makes sense.

A static reading won't work as most bikes don't have a tachometer so we can't create an agreed "standard". I understand the kart clubs meter was at trackside somewhere so let's just use their location or suggest a better one. The start line or half way down the back straight might be a good starting point or anywhere else the majority of bikes are revving out.

We know what happened in HB - that was a disaster for everyone up there.

First and foremost: if you get told you're bike is too loud: don't take offence. Just fix it. Too many Motorhead concerts in the '80's means my hearing is buggered anyway......

[Kendog]

I know my bike is loud, because my wife tells me it is.

So for the technically challenged e.g. me, what can I do to make it quieter?
I am happy to remove the pipe and muffler from the bike and take somewhere if that helps.

[F5 Dave]

Now I think of it here's a place to recommend a Local muffler expert.

Damon formerly of Cycleworks.
Now works from home.

Its a heck of a drive if yer not from upper hutt, but a courier can do it for you. Or bungy it on the back of the bike & enjoy the ride part way over the Akas.

[hmurphy]

I'll be honest, I know my bike is already one of the most quiet ones out there :shifty: but I do want to be on the safe side.... where is the best place to get CHEAP but decent muffler packing?

[F5 Dave]

TM perhaps? TSS stock woven packing. Some people swear by that loose wool stuff but I've never found it any good.

A reversal in flow helps knock out a bit & doesn't have to be restrictive.

Do you mean run the engine in reverse? My carb would probably be a pretty good muffler, not the highest quality casting. I'll see how much TSS want to take off me for me to grab some packing. I'll repost here how much it costs for reference for other people. I'm not sure but I think I have fibreglass mat in my exhaust which probably sucks ass hahaha. CHEAP BASTARD

Last lot I got was the pillow packing matt stuff. 25 bucks I think it was. My bike has always been loud. I am determined to get it shut up over the next week. Will post any interesting finds. First attempt is the big volume muffler I have. If its still silly loud then I will try a vented shroud over the end pointing down onto the track. That work wonders for the megaphone.

[Deano]

Cheap ? Go to the tip or otherwise find an old oven, remove the rear panel and help yourself to the insulation 'wool'.

[hmurphy]

Steve got a new muffler for his bucket a while ago. It's not that long but it's fat as/large capacity (I'm scared of a sentence like that on a biker website). His bike is now pretty bloody quiet, so it looks like decent capacity and decent packing material are the trick. Haha I'll do some dumpster surfing then Deano.

[F5 Dave]

But good quality packing will be better & that is the whole point here. I found years back I failed a sound test at Manfield with some brand new old school muffler packing & repacked it with some Daytona woven mat packing a mate had. 20 min later passed the test.

buy some real stuff & solve the problem.

A smaller outlet is probably a good thing. many dirtbike mufflers for big whacking 4 strokes will be needlessly loud (as they are for big dirtbikes we get out on trail rides). But the bigger outlets can make quite a difference increasing the noise. - Needlessly big if fitted to a liddle 150cc bucket.

Having a reverse in the flow can knock some bark out. Damon for example may be able to do an alteration inside the std muffler if you have something rebuildable, or make an add on section.

[speights_bud]

Don't steal my idea now, BUT this is what i did for noise testing, it was seriously quiet, sounded like a farm bike/Ag200, was perhaps a little too restrictive but it was just for one day so plumbed up properly it would be a bit better. its pretty easy to do and looks kinda moto3-ish too eh :2guns:. With front muffler being a straight through style it was always going to be loud without 'something extra'.

I love my 2 Stroke.
Like Koba said, quietly sneaking up on people is funny.
Many times I have thought there was something wrong with my bike only to realise that there's a 4 stroke sitting up my bum making horrid noises! Quiet is better, tone that shit down! ;)

Only with a bit of dyno time will you really know for sure but you could find the setup worth keeping.

Or the front muffler could be replaced with a resonator chamber and the back muffler made even bigger and more effective.

A resonator at the front would allow the header pipe to be a tuned length that's unaffected by the length of the tail pipe and muffler.

Might be worth a Google and remember you heard about the idea from the 2-Stroke team first .....:laugh:

Yea i will definitely be going back to the setup, it's worth playing around with. There was more noise from the motor mechanics than exhaust. I need to do some serious carb work first though, the 'upgrade' carb came with all sorts of shit internals, diffusers with far to few holes etc. I dunno about Dyno time though that doesn't sound like the good ol spirit of buckets... lol

[koba]

Another point to consider is induction noise, it can actually add quite a lot to the overall noise.

Noise is a problem for us all .... and as the Bucket racings revival is pretty much due to the ever popular FXR.

In the interests of good silencing and power if someone who knows more than we do about the science of 4-stroke exhausts, tuned lengths and a suitable resonator size for a standard FXR150 and want to post their ideas about a quiet performance exhaust for someone to try.

Then TeeZee and Chambers would be happy to put up the dyno time to develop it on some local bike so long as the owner does/organises the construction work and the details are made available for everyone.

[TZ350]

Up close I don't think there is anything in it between 2 and 4 strokes noise wise but the 4-Stroke exhaust note seems to carry further.

So there it is, because we can't race without them, Team ESE is offering their dyno time to help with the development of a quiet performance exhaust system for 4-Strokes.

We are not looking for any old shitter, it has to be an exhaust system based on sound design principles and made from components that anyone can source so they can replicate it easily.

A header pipe 450 to 500mm long from the valve will increase top end on a standard FXR. Then you have to shut it up. Bigger is better. Hamish mentioned Steve's muffler being quite. I gave that to him a while ago. Its good to know it works. It is an old oval scorpion sports bike slip on. Straight through with a 48 50mm bore. It was about 450 long when he got it might be shorter now. Very similar to Gavin V's setup. Any mega boom / resonator would have to be matched to cams and intake. Not much point as you can run a shorter pipe to gain top end. Unlike dirt bikes. If you want to develop a system you would want to be adding a carb and intake to the package. Header muffler and a Akunar 30mm PWK knock off with a trumpet taking it to 205 / 210 from valve. If you can prove it makes more power and is under 95db then people will be keen to make the effort.

[TZ350]

If you can prove it makes more power and is under 95db then people will be keen to make the effort.

Thanks for the info.

I think those specks are what Giggles has been working to and he has 18rwhp.

We are doing some more dyno work on his FXR soon and will post the results.

[hmurphy]

I also think it would be a good idea to not scare everyone off touching their mufflers with all this science talk. I just cut my header pipe where it suited me, and banged on a muffler where it could fit and not hit the ground mid corner. The bike goes completely fine. No issues and is fast enough. I am sure that it could be better, but surely not by a huuuugely different amount.

So if you're scared about touching your muffler and you don't want to spend lots of money, don't let that stop you from going racing if all you need to do is cut your header pipe and put a decent capacity muffler on there. I'm not going racing at Kaitoke until my bike is a lot quieter but it's not a big deal modifying mufflers if you aren't looking for that last 1% of power which I'm not.

Yes your right, we don't want to scare anyone off from having a go, but we dont want to stuff around either.

We have the gear to test things properly and when its all finished those that want to have a go at least have an idea of what something thats quiet and proven to work looks like.

[kel]

Now I think of it here's a place to recommend a Local muffler expert.
Im sure your man is very good at his trade but ...
After trying and failing miserably to quiten my megaphone exhaust it was tossed out and replaced with a unit made by a local exhaust manufacturer, and guess what, I was told it was the loudest in A grade at Kaitoke. Point is you need to be specific about noise even with the guys that make exhausts for a living.
TZ your idea and offer is excellent but the pipe mentioned above has proved OK on a standard camed motor but noisey as hell on mine. That said we're putting cams into giggles bike next weekend so if you can effectively quiten it then the design should apply to most FXR's

[Pumba]

Very similar to Gavin V's setup.

Gavin's muffler is a aftermarket muffler that was off a damaged speed triple that was just lying around (if he is to be believed :shifty:)

[TZ350]

That said we're putting cams into giggles bike next weekend so if you can effectively quiten it then the design should apply to most FXR's

I am away again, back next Monday and looking forward to seeing what we can do. Giggles got his after market muffler from a local muffler shop I think and he says it was reasonably priced. PS Kel I have fitted a TPS to the Beast so we will get that back on the dyno too.

[richban]

Seems to work a treat. Can't really remember but its is not the loud right?

[Pumba]

Seems to work a treat. Can't really remember but its is not the loud right?

Yell it was a shit load quieter than mine was (note the was) so yea it did the job. Based on my limited knowledge on the subject I suspect it is because of the large volume of the pipe.

For the same reason I suspect mine was loud because it did not have enough volume and a large opening. But it has been quietened down with a baffle insert, that hasn't appeared to reduce any power.

[Gigglebutton]

I got a carbon can from Chase on (Maurice Rd Penrose) just up from work. $180 + GST I think. Chinese but really well made and real pretty. They supply car bits but have a box of these for some reason out the back. They sell the bits needed to make up exhausts at trade prices.

[Drew]

Now I have an excuse, I'm reverse porting my bike and rebuilding the pipe!

[Deano]

But good quality packing will be better & that is the whole point here.

Oh have you tried oven insulation Dave ?

I am talking from experience with my CBR400RR - it worked a treat and was definitely compliant.

Got my bike together again today. The new exaust is quieter than the last.

I was thinking these r1 pipes look like a bargin if someone wants to go halves ill be keen to use one as the cheap one I got isnt great quality and these have nice curves for the header pipe to place pipe under bike.

[hmurphy]

Yeah I would have been keen, that's a great price (if going halvies) and the quality would be good too. Someone with a noisy bike (other than myself) should go halves with mossy

[richban]

Got the new muffler repacked and budged on and it is quieter than the last one. Bit heavy but hey it works good. Now just need to get it mounted proper and we are away. And it has a sticker on it from Mr Yoshi. That must make it go better for sure.

They may be shit. There was a Yoshi GSX600 pipe on there the other day for 200 hundie buy now. Heaps of bargains come through the exhaust section.

which there hasn't.
Someone has to man up on the people who are causing issues, and actually tell them they cannot ride, untill the issue has been resolved.
Might put a couple of people off, but they can harden up and resolve it.
I know this is underway... I was talking to a bucket racer today and whom told me his bucket was probably over the limit, but wasn't going to do anything about it, because it was 'probabaly' okay... Exactly the wrong attiude! It needs to be 100% okay.
(Not a personal attack at you if your reading this btw)

We have a wonderful track that we are allowed to use, perhaps the best in the country.. Lets not abuse it and get it right.

Kart Rules

Method A : 1.8m above the racing line - 106.4DBA
Method B : 15m away from the racing line at a height of 1.2m - 88DBA
I'll bring a tape to measure this w/e

-Someone who doesn't race buckets nor never has properly ever :P.

+1 to that. I was talking to a racer yesterday who said that he wasn't going to do anything about his bike until someone came up to him and told him he HAD to, which was a very shit attitude and I told him so. My bike is definitely borderline, but I am packing it out this weekend.

What a stupid attitude, he may find that when somebody does come up and tell him that they also tell him to put it on the trailer for the rest of the day. Happened at Te Puke this year.

If they are set up for noise testing on Sunday, I will ask if we can test the bikes in the lunch hour.

[John_H]

Just packed my exhaust and I think that it's at an acceptable noise level, but that's very subjective. Probably class it as a loudish road bike noise level. It would be a good idea to get them tested at the track.

If anyone wants some exhaust packing material give me a shout, I have a ton of it left over.

Mines well under now.
The $70 one was money wasted but if someone wants it and repacks it should be ok. Its .7kg and idd say just the packing is the issue.

Mine is identical and it had no packing in apart from a tiny 50mm wide collar at one end! Packing definitely helps.

Ah cool you know who has a spare for you. Just say and you can have but its had a shaped end welded on (kind of) for my header though. Started once by one lady owner going to the lowest bidder. All bids exceeding a hotdog or beer will be removed.

Well I repacked my muffler with some quality exhaust packing and tested it out. It's marginally quieter but I think it's still far too noisy. Annoying that I spent money on packing and it didn't solve the problem. My muffler is certainly long enough but I am quite sure it doesn't have enough capacity (isn't fat enough). I'll have to reconstruct my muffler I think. I want to be able to start it up at home without the neighbours wanting to burn my garage down.

We've seen how wwell your SV goes, we know you don't mind cheating. Just leave it as is.

[hmurphy]

Damn now everyone knows I'm cheating. Wish it was easier to get away with cheating.
