When I was noodling around trying to make my stock muffler sound good, the pure stock with insert and everything was right around 86 decibels at 3000 RPM (measured at 1 meter, 45 degrees off-axis, just like most dual sport rides specify.) Nowhere near the 94 decibel cap that was stated for most New England rides I went on. For those less familiar with the decibel scale, an increase of 2-3 decibels is considered audible difference to the average listener, 6 decibels is double. So 92 decibels would be twice as loud as 86, for instance, and 80 would be half as loud! That's a pretty difficult figure to attain without significant restriction.

As to straight pipes folks getting a hefty fine - I'm all for it! Pisses me right off when I'm in the middle of a nice quiet section of music or movie and some jackass comes by the house playing whacky-wrist. It's a stinkin' residential street, not some twisty canyon road, moron!

Can anybody explain my hankering for one of these things? I know they're big, heavy, out of date technology-wise, slow (yeah, I said it), and ugly...
But I just can't shake the urge...

It's a RallyRaid fairing. I just looked on their website, but it doesn't show it. They are in England, cost was around $95.00 and shipping it here was almost as much.

Are you planing on using the other rotor.........putting dual calipers on the front,if not i`d toss the other rotor..loks great though...nice job..


Good eye, Brian. When I put those wheels on the stock L forks, the right side of the wheel looked funny with only the mounting protrusions for the rotor showing. They stick out pretty far from the center of the wheel. So I just threw a rotor on that side to make it look balanced. I've thought about adding the other caliper, but with the price of Ohlins forks, it may not become a reality. In looking at the left fork with the caliper mount, using it on the right side would involve quite a bit of modification, but it's still an idea.

Lean is what I'm thinking too. On the pilot I'm guessing. There must be quite a bit of flow difference between the uni and the K&N to cause this much difference. Gotta love CV carbs.

Painting it will reduce the effectiveness of the cooler... Here's a pic of mine FWIW...

Looks like they completely revamped their web site in the last week or so. They seem to be focusing on KTM bikes. I just bought one for my XRL, I bet if you emailed them they could come up with one. Paul was very helpful.

Olderslowerguy, your fairing mounting looks very vertical. Was this a style choice or is there something in the fairing design that prevented you from leaning it back a bit?

New riding buddy, he's a little beast on an Xr, thought I could outlast him but my butt was screaming for a better seat long before he was ready for a break.

The CV carb is very finicky about airflow and turbulence. There are combinations of filter, washer, spring, and drilling I am convinced that will always give grief no matter how the jetting is tweaked.

One of these things??!!? Big, heavy, slow and ugly. Try not to drool too much.

I think you may be right about that. Only reason I put the K&N in is I didn't have a clean uni. It surprised me the difference it made just in the one throttle position.

I'm pretty sure that the 80 decibels limit is not a typo. The sound test for the EPA stamp is considerably different the one you did. It has been year since I read how it was done, So I won't try to post that here. I would probably be wrong. In the EPA test the meter is a lot farther from the bike, and the angle is probably different also. The difference in the test accounts for the lower decibels. The XRL with stock pipe meets the EPA's 80 decibels limit or it would not have the EPA stamp on the muffler and could not be sold new as a street legal bike in the USA.

You are correct...I had to make a bracket to attach to the CRF upper triple to mount the headlight assembly to. That moved the entire assembly forward about 2". I made a new lower bracket that the bottom of the fairing fits in to, and just didn't make it come out away from the lower triple far enough. As it sits in the picture, the headlight shines on the ground too close to the bike. I made an adjustment to the lower bracket this morning, the fairing now sits with more of an angle to it.
