    I don't think you will find alot of factory add on's. FMF has a slip on exhaust But no special head pipes that I've ever saw. You might check into increasing the compression slightly and make sure you add the upgraded base gasket. that with a carburator off a drz 400 might be what you are looking for.

    sorry, I read DL650 for some reason. SV stuff will most certainly not work on a DR650. Still, you can do the usual carb, airbox, exhaust, high comp, big bore etc stuff. Its pretty much up to how much you want to spend and how much hp you want. You could even install a boondockers kit if you are in a real hurry to get somewhere.

    Saitune (sp?) does full exhaust for the DR and I think yosh might as well. High comp and big bore pistions are available and you could always get a cam ground if you really wanted. Big, flat slide carb couldn't hurt either (first guess would be a 41mm FCR).


    This is a good place to start

    on the keintech site they say that the FMF Q2 weighs 5.5lbs and the stock ~15lbs. Is that close? I mean that is a llooooott of weight to drop. I am in the market for a DR and can't help but look at all the possibilities. Looking to build a mainly commuter, occaisional long hauler, and who knows how much off pavement.

    That is about right. I haven't weighed them, but the stock exhuast on most bikes like this is generally made from a lot of really heavy mild steel. I know just the muffler on my dad's XR650L has got to be close to 15lbs +. They approach to exhaust on these dual sports is very very different than on a close course machine (where you'd be lucky to drop .5lbs in most cases).

    have fun

    Most important before you change anything to the engine, is remove the snorkel on the airbox and fit a Dynojet Stage II kit. Imho this alone makes more of a difference than any aftermarket exhaust.

    And so does lowering the gearing.

    you get squat from exhaust system
    maxcool is right on the money, airbox & dynojet
    leave exhaust alone, if you want to spend on even the cheapest exhaust, your money is 1000% better spent on a flatslide.
