    You can find many threads on various forums going back 5-6 years about Dual Star not answering phone calls. Maybe they finally decided there's no reason to pay a phone bill if they're not going to answer the phone anyway. :huh

    This is a topic that does interest me, but with my current work load I don't think it would be in the cards anytime soon.

    While I've only taken off the cap on my carb once, and it was over three years ago, to fix the overly lean mixture endemic to the DR, I recall leaving the tank, seat, side panels and all cables attached to the bike. Just loosened the carb boots, maybe loosened a carb cable or two, and rotated the carb so the cap was accessible from the left side of the bike. No sense making a big production out of an easy task... :lol3

    According to these graphs: (Procycle, I hope you don't mind, if you do just PM me and I'll clean up the post)

    And

    You should be seeing around 36 hp and 32 ft/lbs. when I uncorked my dr, and jetted it properly, (stock exhaust, cut-top air box, KNN filter) it felt like it ran crisper with more low end power. When I did the carb upgrade, that was the most noticeable increase in pep. It almost has that fuel injection, instant power feel. I recently did the hayabusa muffler upgrade, and I haven't been able to ride enough to pin point my jetting properly, so I can't comment on how much different that feels. The exhaust note is much better, I can tell you that!

    Thanks planeman! If the base line is an uncorked bike I wonder what the bone stock, off the show room floor numbers are in comparison?

    just a quick question about those torque/hp graphs.

    Were the exhaust, airbox and carbs (not jetting) the same for each level of modification?

    What pipes and carb were used?


    The torque # on the 780 kit is making me drool.:tb :ear

    Bone stock peaked around 32-33 hp.
    Individual DRs vary quite a bit. There is one local 'uncorked' bike that posted just over 39. (cut airbox, Q4, jet kit).

    Buh.... so this shop said I need new keys, new battery, they want 1200 to get it running again from the fried wiring harness. They couldn't tell me why it went up in smoke.

    Picked up this bike about 2 years ago and absolutely love it. I'm a photographer and use it to
    go into the Everglades here in Florida. I have the Pelican case on the back for my camera equipment and it has
    worked out great.

    I took out the snorkel, did the needle shim and the mixture screw...could not believe how much better it ran after these
    simple mods.

    Here's a pic from one of my rides into the Everglades

    Here's a couple of the pics I got of the Endangered Florida Panther during my Everglades ride..

    The 780 kit is BIG fun.

    I bet it is,I was wondering how long a DR650 runs with 20 more HP then stock? Has anybody ran one very long?

    The DR650 motor is pretty under stressed, no? ... my guess is the bottom end can handle it OK. The Oil cooler being a big plus for handling the extra heat from 20 more HP.

    My concern would be the trans ... and 3rd gear specifically.

    Probably be fine if not abused.
    Too few examples out there to get much feed back.

    Are you using the stock tank? My IMS goes down pretty far. I can barely see my Carb without taking the other stuff off.

    That was my first concern. With all that torque, you could always go from 2nd right to 4th.:D

    As to abuse, "probably fine if not abused" why bother then. abuse it stock for the same effect as a babied 780.:lol3

    Yeouch!
    I would buy a used harness (eBay, etc?) and change it yourself.
    No need to get new keys that I can think of since the ignition wires plug into the harness.
    Even if the wires connected to the ignition burned you should have enough to splice in new.
    I know very little about wiring but replacing the complete harness with a new (used) harness is easy if you just do as suggested to unclip and reclip one at a time.
    I am never happy with any work a shop does so I end up doing my own work though.

    Just my 2c

    Getting close to 2-1/2 years now. No problems whatsoever. The thing is, 98% of the time you aren't using any of the additional 20 HP. It sure is handy when I want to pass a truck uphill.

    Parts finally arrived so....Pine-Sol dip, new main jet, new pilot jet, and new KTM needle and the hesitation off idle is now completely gone. Only issue I am having now is some pretty obnoxious decel popping at > 1/4 throttle. What I mean by that is the decel pop is minimal to nada if I don't get on the throttle much. It's only on decel when really opening it up that the popping starts to get bad.

    In an effort to remedy, I tried adjusting the fuel screw, seem to improve a bit the wider it's open, but still present no matter what. However, it does go away if I throw the choke wide open...

    I set the KTM needle on slot 3, right in the middle, as this puts the spacer at the exact same location as the stock needle. I gotta say, these needles look nearly identical to me. Is anyone with me in suggesting that I try raising the needle up a slot and see what happens?

    Almost there.....:D
