Ardmore - need support!

[telliman]

Depends.
Is it loud?

arnt they all??

[cs363]

so wth my new 250f im running a ti4 exhaust system,does this put me in the loud bike catagory? do i need to change?

If it has the longer cone shaped end cap and is properly packed (and has the spark arrestor installed) it is probably running around 97db.
There are new inserts available to further reduce the noise output now available from Pro Circuit, these will drop it to well under 96db which is now the legal requirement for MNZ events and is equal to or less than most stock exhausts.
Give MR Motorcycles a call they should be able to get one for you

(it's hard to be specific as there are also different length cans on those pipes as well - a lot depends on when it was manufactured as to what the noise output was, as the whole noise thing has been fluid in the last few years, all the new (08-09) pipes have the new insert/end cap. If you had one of the older pipes that had the stubby end cap and a short can these can be as loud as 102db)

The talk is that even std exhausts are a bit loud for Ardmore ( and everywhere actually) and if Ardmore is allowed to continue there may have to be something done with some sort of insert. I had a discussion about the new CRF450 and the decrease in inner tube exhaust diameter on the latest model that has made it significantly quieter vs the older models. So it looks like manufacturers are tackling this issue. I was told there was some comments made about a perceived reduction in power. But even if we have to fit some sort of restrictor insert specially for Ardmore its the same restriction for everyone. And lets not kid ourselves who the heck gets to the end of their throttle stop in every gear at bloody Ardmore on a 450. Nobody anywhere I would pick. Shit even on a 250 four stroke you wouldn't tap it out at Ardmore would ya!!! I'd rather fit an insert than close the track thats for sure!

So Telliman the answer is it probably will be loud for Ardmore, especially if they put a DB level on the decision, but I think we just have to wait and see what they come up with. Its Looking like all the owners of pre 09 4stroke bikes are going to have to tackle their DB levels if they want to go anywhere. Hehe that'll teach you to go 4 stroke!!! HEHE looks like they'll be going "putt putt putt" in the future while real bikes will be going RING A TING TING!!!!!!
Whats it like to ride compared to your KX250, power? handling?

[NordieBoy]

arnt they all??

Not compared to a YZF passing you on a cross-country that's blown it's end-cap and packing somewhere on the course

Scares the shit outa ya.

RING A TING TING!!!!!! Bling.....

im going to laugh the day everyone finally realises 4 strokes are shit and go back to 2 smokers. they are allready lighter, quieter, more powerful, cheaper to buy , cheaper to maintain, easier to work on, lower maintenance, more fun power to ride, shit what more do people want in a bike?

[Ktmboy]

RING A TING TING!!!... Lol
I think this means the same as " Check the Donkey"

More torque?

[Reckless]

HAHa Nordie us 2smokers are sick of all the "talk". We know whats better on the wallet and the ears!!!! of to bed "ring a ting ting"!!!!!!!!!! night all!

[BIHB@0610]

PM me if you want any help. I know a bit about the RMA, especially the process from here on in.

another one who needs to ride a modern 2 smoker i guess.

the modern 2stroke DOESNT have a dyno graph that would resemble this diagram im going to draw with dashes and slashes ________/

All done and dusted now Planna last meeting was last Monday. Thanx for the offer though!

Untill a few weeks ago the only 2 strokes I'd ridden were modern ones apart from a 1974 TS400 which had good grunt down low and a PE175 that did have a torque graph like you drew.

yeah a lot of 2 stroker baggers seem to think all 2 strokes are liek the PE you refer to or "just like the 80 i rode 10 years ago"

regardless, this thread is about noise, and how we are going to make a difference in making it lower. i dont know anything about mufflers but there must be a way of making them quiet witout being too restrictive, those four stroke factory mufflers are physically quite large so theres a fair amount of room to play with.

theres some car exaust, could something similar be implemented?

[Danger]

Perhaps purchase a luxury exhaust of that guy off Trade Me?
