Dear Procycle and motolab. I have a dyno jet needle and main jet with an opened air box and my bike runs like a charm with no detramental side affects that I can detect, Runs way better than it did in its standard configuration.
Just my two bobs worth.

regards Noel

Thanks for the braking info LucasLeader and Adv Grifter. I think I'll start with new fluid, braided lines and new pads and take it from there. I'm not looking for huge gains, just a bit more bite and feel after a few "moments" commuting.

Thanks.

Mine cracked from a mis-aligned mid-pipe but not near the weld...

25,000Km (~15,500 miles). Not sure really. It's had 2 previous owners that I know of and the guy I bought it off said he mainly ended up using it for trips down to the shops (he was in a rural area so it was a decent ride).

Probably is a damn good idea I give the internals a check I guess...

There's another DR thread for folks who are extra sensitive

How is it I can sit at a bar with a guy, have a heated debate, tell eachother "awe bullschmitty and flippover" then buy each other beers talking about the hottie that just walked in the door all without any hard feelings?

But on the interwebz forum, folks get their mangina all dry and chaffed.

Relax already!

Brisk Commute

I had a nice brisk commute n the Sacramento CA Area this morning on my 2006 DR650!

27 degrees fahrenheit @ 80 miles per hour actual = wind chill effective temp of 4 degrees F - burrrr!

No electric gear I might add.

Done on my dr bought new in 06 with about 40,000 miles and with DynoJet Kit, slide drilled and side cover removed, installed and working great for 35,000 miles or so (still power only wheelies and gets an avg 46 mpg)

I would pay particularly close attention to:

The float needle's tip: Check with and without magnification for a witness line where it has been contacting the seat. If one is found, the float valve either leaks or will begin leaking soon, causing a high fuel level or overflowing.

The needle seat o-ring: Make sure it fits snugly and is not cracked/hardened/deformed/shrunken/otherwise damaged. If it's not in good shape, it will leak, causing overflowing.

The slide guide: Make sure that the indentations concentric with the bore in the bottom corners adjacent to where the slide bottoms are still .010" (.25mm) deep or more. If they are not, the emulsion tube is at risk for wear. See http://www.moto-lab.com/gallery/view?itemid=300, http://www.moto-lab.com/gallery/view?itemid=301, http://www.moto-lab.com/gallery/view?itemid=298, http://www.moto-lab.com/gallery/view?itemid=299, and http://www.advrider.com/forums/showp...ostcount=68638.

The slide: Make sure there is no vertical grooving on the downstream side and that the lift hole area has not been increased by drilling. Drilling causes excessive slide guide and slide wear, which in turn accelerates emulsion tube wear. See http://www.moto-lab.com/gallery/view?itemid=304, http://www.moto-lab.com/gallery/view?itemid=302, http://www.moto-lab.com/gallery/view?itemid=303

The emulsion tube: If the outlet has ovaled, the mixture will become overly rich at low rpm at all openings. The wear can sometimes be hard to see, but keep in mind that .0004" (.01mm) of wear will be discernible on the dyno as an approximately 1 percentage point change in CO (i.e. it the CO was 4% before the wear, it would now be 5%). Sometimes spinning the tube between your fingers can help you see the wear, as can inserting something known to be round, however if the slide guide is worn more than .010" (.25mm), you can pretty much be assured that the emulsion tube is worn. See http://www.moto-lab.com/gallery/view?itemid=305, and http://www.advrider.com/forums/showp...ostcount=33350.

The pilot jet: I recommend replacing it as a matter of course.

The float height: Using a float height setting tool, set it to it to 14.7mm.

Derek

Same here.
I think both Jeff and Derek have good points and both are right.
I can say that I could never get my DR to run well shimming the stock needle with any combination of jetting.

Sure, it ran, but I knew it wasn't it's best. But I think Derek was always talking about a NON USA OEM. These have notches ... unlike USA needle which are non adjustable. I think Derek also mentioned a few KTM needles as perhaps being a good fit to the DR.

The DJ needle has (for me) made a huge difference overall. I'm sure there are better needles ... and since my DJ needle now has about 35,000 miles on it, I'd be happy to try something else. My bike has never been dyno'd so all my assessments are "seat of the pants".

Derek, I'm in the Bay area ... if you can recommend a better needle I could buy ... I would try it out.

I can see some slight wear on my current DJ needle, but bike still runs strong; starts, idles well, around 50 MPG, 102 MPH (measured) top speed (prone) and power wheelies in 2nd gear ... no clutch.

155 main, stock Pilot, open air box top, Twin Air, stock muffler, 1/2 turn out on fuel/air screw, no header weld grind .... 50,000 miles. Throttle response on my bike could be crisper ... but not sure the DR motor is really ever a "crisp" revver. It's no Triumph Daytona after all.

Does your bike have the airbox mod? What pipe does it have?

Derek

Right. That's embarrassing. Anyhow...

Well I guess that disqualifies the bike from the possibility of being the "definitive" candidate for tuning demonstration. However that certainly shouldn't be a reason not to tune it if that's what Mr. Grifter would like.

Regards,

Derek

By my "seat of the pants" evaluation, it's tuned fairly close. But as mentioned, my DJ needle shows some wear, may need replacement?
And this bike has not been on the dyno.

Given my basic tuning set up ... what needle would you recommend to maintain status-quo or maybe go one better? I suppose I should check out your thread on Vendors?
