    I have provided evidence in the form of a dyno chart with a CO trace that the DJ needle provides poor results. You have neither provided evidence that the DJ needle works well, nor that the non-USA adjustable OEM needle works poorly.
    Where do you think knowledge of the trends comes from if not from tuning, seeing what the results are and then keeping track of them?
    And well after that.

    hey y'all! its' been 18 months since my accident and finally got the DR back in the dirt in nicaragua where she lives. first ride on her since the accident. some may remember what happened but if not no biggie. bottom line is i still limp and probably will for life.

    anyway, holy SHIT did i miss this bike! been riding the big pig on the streets since december but that is boring.

    took me a bit to get my dirt legs back but managed a three hour semi-rough doble track ride without falling. the route had some pretty interesting hills, both up and down. haven't gotten the helmet cam back up yet so no pics or vids. sorry. but here is our gps track overlayed.

    now, even before my wreck i never made it to the level of advanced dirt/trail rider by any stretch of the imagination. and there were always a few questions about what to do when. so here goes...

    1. on super steep declines when 1st gear engine braking doesn't quite keep you slow enough, what is the best braking technique?

    2. downhill, rough terrain. stand on pegs? weight forward or back?

    Mine with open air box, k&n filter, fmf muffler, adjustable OEM needle, runs great.

    Broke the upper chain roller out of the frame. Now my DR matches my wife's. I sealed up the holes in the frames with JB weld. I never should have put that roller back in.

    1. Roll in 1st and brake with the front until you're moving too slow for idle, then roll with the clutch pulled and use both brakes. Be careful to modulate the front brake so that it doesn't lock. You may occasionally want to drag the back tire around, but most of the time will be best with both wheels turning.

    2. I get my weight as far back as practical. I usually stand, but my weight may be so far back that my butt is on the seat. If it's a short drop with an open runout, I may just lean back and wheely down.

    Yet again a lame attempt to deflect from the original point. My comment was NOT in any way related to the DynoJet needle. If DJ needles did not exist my comment would be just as true and valid. I don't really care what your opinion of DJ needles is and frankly I'm very tired of hearing about it. It is not pertinent to the point I made.

    Can't you read what I say, take it at face value and respond to the point at hand? I guess not. If you can't stick to the point why respond at all? Just to turn it into an argument? What a waste.

    You are the only rider I've heard of that feels successful with this setup. I'll concede that it might be workable at high altitudes. I'd love to know all the details of your setup.

    What needle clip position? I'm just about to install the adj needle for running 1,000' lower range than you.

    It would not be valid regardless of whether DJ needles exist or not.
    You must care what my opinion is, or else you would not continue to comment. I'm sorry you're tired of hearing about the DJ needle's shortcomings, but unfortunately that's not a good reason for me to stop contributing here.
    It's pertinent because people tuning the BST40 carbs on their DR650s will need to select the needle that works best. Unfortunately that is a comparative endeavor that ideally involves becoming aware of the shortcomings of the DJ needle (as well as the advantages of the non-USA adjustable OEM needle), but we can leave it out if you like. Please provide a dyno chart with CO trace that demonstrates that a non-USA adjustable OEM jet needle is unworkable.
    I could ask you the exact same questions.
    Indeed.

    There is a wide variety or tires made for DR650. I've used AT LEAST a half dozen different ones over the years. For "tooling" around and commuting I'd go with a street biased dual sport tire. These are pretty HD tires, give long life and are EXCELLENT on pavement but not great on gravel but do work. Considered 80/20 (street vs. off road) They are all weather and good on wet roads ...but not so good on muddy dirt roads.
    Next is BUDGET ... how much you wanna spend? How far you wanna go? :D

    The most popular current tire in this class for the DR650 is probably the Shinko 705. A great tire and affordable. Best value.
    In this class you also have several other EXCELLENT tires:
    Avon Distanzia
    Michelin Anakee ll
    Metzeler Tourance
    Pirelli Scorpion Trail
    Kenda 761
    Bridgestone Battlewing (140 rear)
    Dunlop Trail max TR91

    the other technique is engine off, then use the front brake and clutch as your brakes. usually reserve this one for tricky downhill sections where you might want to have the option of getting both feet down or cant get your feet onto the pegs like with deep ruts. good idea to practice this one before you need it too, its a weird feeling letting the clutch out and pulling the brake lever in at the same time to slow yourself down

    :lurk

    At 2200' asl, with a Jesse of kientech.com modded DynoJet kit setup (Jesse's open airbox specs...), 155 DJ mainjet for stock exhaust and Twin Air filter, adjustable fuel screw 1 1/4 out and IMPORTANTLY the needle clip set leaner than suggested, with the clip 3 down from the top (to eliminate the off extended idling flat spot, with the clip set 4 down from the top), my 07 starts great, pulls like a bear and gets great gas mileage.

    What's not to like. :evil :raabia

    Derek,
    I hope you get a chance to get your hands on a few DR650's for some dyno tuning. Do you have a dyno on site?

    Funny story there about Mark.
    I have been present for some AMAZING LECTURES over the years ... always very educational. Unfortunately with me ... in one ear, out the other. :D He is a really good guy ... and so smart he's off the charts.

    I get what your saying about the CO trace and DJ needle. All I can confirm is my bike runs like stink. The new carb (about 15K old now) shows no sign of emulsion tube wear or slide guide wear like my first one at 30K miles.
    I just bought another ... BRAND NEW BST ... as a spare! :thumb But I do intend to try some different needles. Your non USA OEM one, Pro Factory's... and compare to my old (but not yet worn out) DJ needle. I can't afford dyno time ... but am pretty tuned into the bike.

    I must say however .... I thought I may have detected some minor pinging on my ride last week. At high altitude (over 8000 ft., lugging under load with regular gas, 95F temps) Next fill up I switched to Mid Grade fuel and never noticed pinging again. :clap I am not positive it was pinging ... but could have been.

    First time I have ever noticed pinging ... but we were climbing STEEP grades ... so maybe that was it? I was pleased that the mid grade boost seemed to help. Or was it all my imagination? Problem is ... many times in the boonies only regular is available. I intend to follow up on this and push the bike some more ... see if it's really pinging or just drive line clatter ... or what?

    I am going to be getting a dr250 tail light for my 650 and was wondering why the procycle tail light is $30 more than the keintech tail light. Is there any major difference between the two? I have heard plenty about the procycle light, but has anybody found problems with the keintech kit?

    Sorry to hear that Klay. How did it happen? I haven't removed mine yet as I have not gone and really taxed the rear suspension.

    I called Kientech last week about the DR250 light kit. They aren't selling them anymore. Suzuki raised the price a lot. That's probably why ProCycles has gone up dramatically.

    I just ordered a Maier Enduro Taillight. $24 It's what I had on my last DR650 and it was fine. Doesn't fit the opening exactly but it's close. Never had an issue with the old one.

    If you go this route, get the larger of the 2 sizes.

    Yes, it has a new superseded part number and a tiny detail change in the construction plus a gigantic increase in the price. It's my belief that Suzuki has sold so many of them that they think the original 250 taillights are failing. Certainly between keintech and ProCycle we've sold far more taillights than Suzuki ever sold DRZ250s here in the US.

    I am however working on a new option. ProCycle recently acquired a 3D printer. I'm using it to develop our own replacement taillight that will be a direct fit into the pocket in the fender.
