Shoot me a PM and I'll email you the file, you can take it to any local sign shop and they can cut it for you. I have a graphics plotter but to get the two colors we have to cut two stickers, then re-align the parts all back up. A little labor intensive. They should be real cheap to have cut.

Thanks,

Some of you Northwesterners might like this one as well. It's the 1st one I created.


You won't want to make it any smaller than 6" wide.

I ran this through a vector program to clean up the aliasing (aka jagged edges) and saved it as an eps file. An eps file can be resized and look the same. A lot of vinyl cutters can take this as an input too.

Here's a preview without the jagged edges:



(not bad for a techie but maybe a graphics guy could clean it up more )

Highfive - Sound Test Results

Well, the howling wind finally died last night and I was able to complete my sound measurements this morning. By the way, I'm not sure how the rest of the country faired, but some kind of double bad Northern blew through Oklahoma like a freight train. Sunday afternoon it was a balmy 76 degrees, then 6 hours later it was 25 degrees! Anyway, I digress....

For you Technomaniacs, I followed the sound testing procedure covered in this link: http://www.thumperfaq.com/sound.htm

Well, as best I could anyway. Kind of hard to do it perfectly without a tachometer. Here's a photo of my sound meter in action, which anyone can buy from Radio Shack. Its an affordable, accurate unit. I've had lots of practice with it as the Sound Engineer at my Church. It works!





I don't know if I was below, at, or above the rpm for 1/2 peak power. Don't really care. Who knows how the manufacturers actually rate their products. Since I didn't have a Tach on Rē, I had to devise a plan for consistency to easily apply to each bike. So, while the actual measured numbers may be different than manufacture ratings....or even some official certified field test....I think they are decent comparisons between each bike.

I measured sound at the following points:
1) Idle
2) 1/4 throttle
3) 1/2 throttle

No, I didn't get all scientific and physically measure/mark these exact points on the throttle for each bike and hold it there perfectly. I just turned it to where I felt was right. If you want it better, do it yourself!

Drum Roll........here are my results:

Pipe- Idle- 1/4- 1/2

Stock w/ SA- 90- 103- 105
Stock w/ Graves- 93- 105- 110
Powerbomb/Q4- 91- 104- 107

KLX250 w/ Q2- 94- 99- 107

Interesting results on paper. Everyone knows the sound of the stock pipe. It is definitely more quiet to the ear than the Q4, but actually produces similar measurements. At least not as far off as you'd think. The differences in my numbers could easily be related to throttle position...due to my unscientific method.

I can tell you the sound of the Q4 is definitely different. The Graves Insert and the Q4 both produce a deeper tone of sound. Maybe that is what we usually interpret as being "louder". I know that I felt I could sneak around in stealth mode with the stock pipe & can. But I do not think that I could go undetected with the Q4. Maybe its all in my mind while I'm sitting on the saddle and not such a big issue from a distance. I donno.

I do know Zadok's Powercore seems louder than my Q4. But, it was too windy to test his the other day. We'll post that result later....

Thanks for the comparison HF.

Had a feeling a DB test would show that the Q4 is
really not that loud - just more of a different
pitch/frequency than the stocker.

FMF rates it as 92db in their description.

I don't know how accurate that could be. In a season of AMA Db testing I have yet to test a MXer (with any of the thundering exhausts from FMF, Pro Cir, WB, etc.), at higher than 102 Db at 50% max RPM.

For comparisons sake, AMA MX sound at 50% max RPM is now 96 Db. =/-1. No way a stock or Q4 piped bike is near/over 100 Db!!! The Q4s we tested were all at or below 92 Db, 20" from tip of muffler.

Actually that's part of the cutting process. When you're ready to cut/plot the image it's vectorized first. Also the image is very large...When scaled down for actual printing there no concern regarding jagged edges (at least it hasn't been for this particular graphic).

Guess which wannabe lurker (well, mostly lurker) has finally joined the club.....



Just before winter can be a good time to find some deals. This one was a Yamaha demo bike that was on loan to a local trail riders organization. Way cheaper than list, a few nice add-ons and a 3/4 warranty to boot!

Sure is gonna make for a long winter though..

HF, I don't care how scientific or accurate your tests are, it's the deltas that are interesting. Looks like the Q4/powerbomb combo does pretty well compared to stock - looking forward to hearing your general impression of sound levels once you've had a chance to live with it a bit. btw, thanks for your comments on the stabalizer... food for thought.
