Dynojet kit is far too rich. Their needle taper is good but main jets are way way too rich. Use their needle on 2nd clip then go with an OEM Keihin 142 main jet or if you want a bit more mileage go with a 140. Properly jetted the KLR will give you 46-50 mpg in mixed riding.

So, I'm reading a recent Dirt Bike article on the KLR650. The author claims to have gained 7 hp (from 33 to 40) with an FMF pipe and JD jet kit. Seems that most others around here tend to disagree that such a large gain is possible.

Here's a dyno chart http://www.pbase.com/image/110004615

I'm confused

I hate to say it, but it does seem optimistic, unless the JD Jet kit is that good.I doubt it.
I've often wondered about the Jd kit on the Klr but no one seems to have done much testing.
The Ktm guys swear by the Jd kit though.
Which FMF muffler was used in the test ?

Have you seen Patmans big dyno writeup ? He could not get 40 and had alot more mods done.

I recently put one of Parabellum's re-designed 1st gen klr shields on my 02 and i love it!

Plenty of wind protection and it doesnt get in the way off road or have big brackets all over the place either

Correct me if I'm wrong, but I think JD bought a GenII KLR, then made a needle to improve on the stocker. Almost all JD and DJ needles have a more aggressive taper than the stocker, except for the JD KLR needle. It looks like a pencil with a rounded off eraser.
Strange, but he must have a reason for it.

I am no expert but as i understand it the size and shape of the needle are important as well as the position of the needle to the needle jet. It appears from his web page that james dean jetting used a gen 2 bike; he provides pictures and dynographs. All I really can say is that the change woke my bike up as they say. I dont have access to a dyno nor do I take accurate gas milage figure but I usually get 49 to 50 mpg before and after the jetting. This is the second bike I used it on and am pleased in both cases.

JD Needle kit...I use an Air/Fuel meter with wideband O2 sensor and have tuned/sniffed a number of KLR's the last few years. The DynoJet, JD and KLX needles all offer better fueling compared to the stock KLR needle. Dynojets recommendations for main jet and other changes are wrong but off the shelf JD's kit is pretty good. The KLX needle kit with either a keihin 140 or 142 main jet along with a couple other minor changes is pretty darn good too.

For those who already installed the Dynojet kit simply convert the main jet to Keihin sizing and if you have a stumble when you twist the throttle you'll need to fill in the 1/8" hole in the slide the kit has you do and redrill to 7/64ths.

Isn't the KLX needle and DJ needle more tapered, whereas the JD is exactly opposite?

Available in "kit form' from a number of places but I'd suggest www.eaglemike.com If you want to order from your local kawi shop its part numbers; needle (N1TB #16009-1794), spacer (92143-1667) and clip (92037-1401)

I never looked at them side by side but rather through A/F graphs on my laptop. All the needles performed well I just found the KLX and JD kit worked better in real world riding. My A/F meter is portable so I can actually go out and ride the bike under real conditions vs sitting on a dyno. Granted, tuning todays supersports bikes gets a bit difficult at WOT settings as its hard to find a road long enough and clear enough for all RPM's but thats another story lol.

Conspicuity lights.

I shamelessly stole this idea from DrMoto in the KLR250 thread. These 1.5W LEDs are from superbrightleds.com and the pair was less than $15 shipped.


These brackets go on the upper mounts for the front wings.

And here is one mounted (you can see I added two more holes for a zip-tie around the power cord).


These are out of the way but not as shielded as it looks in the photo -- I can see them from about 45 degrees.

EDIT: This is where I got the lights: http://www.superbrightleds.com/morei...watt-led/1141/
