Quiet is a good thing. Loud pipes lose riding areas.

Why do loud pipes lose riding areas?  Isn't that mainly because of neighbors complaining?  It makes perfect sense to make this association when you're talking about a track nestled in the middle of suburbia, but I don't see how a riding area 100 miles away from anywhere would be affected by noise.  Yet, I think I have heard of some areas like these being shut down.  Is that because of noise, in that case, or other issues like revenue or lawsuits?  That's not a rhetorical question, by the way, I'm genuinely curious to know what causes riding areas in non-developed areas to close, and whether sound is one of the big issues in those cases.  Regardless, though, I don't think a YZ250 with a Shorty is going to be loud enough to close down anything.  We know what the loud bikes are.

We don't all live where you do JETZ. I can't think too many riding areas "100 miles from anywhere" in most places. One place I ride is only 2500 acres and you can't see houses or anything from the trails. Yet the club gets many complaints about noise and have almost lost their lease a couple times due to noise complaints from neighbors. I remember two tracks that were closed down here for noise in the 1990's, before the 4-stroke boom.

Loud bikes are NOT faster, they just annoy non-riders. And many non-riders consider the two stroke braap to be more offensive than the 4-stroke boom. When I bought my nephew a TTR125 in February it had a full FMF PowerCore exhaust and was LOUD (seriously loud). After 2 months we traded it for his CR80 and we have gotten three complaints from neighbors about his CR being too loud. Yet the not one complaint when he had the TTR, which was truthfully at least twice as loud if not more so.

I have come across the same thing in regards to 2 stroke noise v 4 stroke.
I always find it baffling when people say 2 strokes are loud. ???
When i had the RM a mate was telling his son and the son said, Oh one of those loud bikes. ::) He was 10

You should know by now not to try and argue with jetz.
Its like argueing with your wife.
No good will ever come out of it. :P

This is true, in the Pittsburgh area there are patches of public / private land, lots of it, between developments and suburbs.  Like the South park dumps, even where I rode Trax Farms.  I used to ride a coal path that went from Library to Peters (the old Montour rail, which is now an offical walking path) and it was right behind houses and under overpasses.  

Truthfully, Jetz is right out here the riding areas are in the boon docks, if anyone lives out there they are like the people in "The Hills Have Eyes".  

They don't really enforce the sound in the woods as much as I heard they do out in the Dunes areas.  But still, the woods are shared with Bicyclers, Hikers and Campers so even if no one is living there you have some one taking a video of an eagle taking a crap on a deer on a hiking trail it may be interrupted with the sound of 2 stroke and he may complain.  So even out here there is a chance, even though slim, because if your bike is louder than 99db and they check they can give you a ticket.

Last year we were out riding, my friend on his 1981 YZ250, 2006 YZ250F and another guy on a 2001 CR500 with me.  The guyon the '81 fell and instead of waiting there, him and the guy on the YZ250F left.  Well, they both got lost.

Once we realized they were gone we went looking all over for them.  I couldn't find them anywhere.  Then we went back up to where one of the trails began and turned off our bikes.  I heard the YZ250!  It's got a unquie sound and that bike is LOUD.  Infact, he was over the mountain and in an area we never ride into since there aren't any trail.  But I heard him!  We followed the sound and found them! 

So that bike is quite loud.

Well, here, it's not an issue of loudness, as we ride basically right in town, there is bush all over, like, who is going to stop us from riding? No police officer is going to ride their car off road like it's the dukes of hazzard... But, I do agree, loud does not make a bike more powerful, but, there are a lot of bears around where I live(the other day I saw 4 bear cubs in one day) and so a loud bike is good. Although, my bike is particularly loud, it has an r304 silencer, and i need to get it repacked, but no matter how hard I try, I can not get it apart to repack it, I have the repacking material, but, can't get it open. Anyone have any ideas?

You would like I would learn eventually in both instances, I guess I am stubborn.  :)

On my nephews CR80 I actually had to take a thin screw driver and tap it in all the way around between the cone and the silencer body to separate the nose cone for removal. I couldn't get it lose any other way. Then once I dug the old packing out, cleaned the core and inside the body, repacked it, I took a ball peen hammer and tapped the silencer body back into shape before I installed the screws. I honestly don't think that was repacked in many years to be that stuck and nasty.

I thought this was a picture thread.. :-X
I think quiet is better, the less people that know your there the better. And look at it this way, is all that noise really worth the 1-2 horse power? maybe for racing but for woods or dunes riding this is a must because of idiots who can't believe that there is noise coming from the riding area they just moved next to.

Pictures are difficult.  First you have to take them, then you have to get them off the camera and finally you have to upload.
