    I was able to get a little work in on the exhaust this morning. I used the FMF KX 125 silencer with the FMF KDX internals and stinger cut to fit...

    Lower radiator crossover hose just clears head stay mount...

    With the motor sitting in the forward rotation the return hose is against the motor, so I will just have to keep an eye on it for wear...

    And I she lives..I rode her around a bit today. I already feel the difference with the Ron Black mods. With the same jetting, the motor feels to have more bang through its range and it even feels like it lugs better. I suspect the top end will not have changed much with a woods pipe on,but the gears roll quicker with the new found acceleration.

    I still have a few things, including replacing the the left side radiator... before hitting the trail.

    Damn nice work! That thing looks factory for sure. I bet it's a blast to ride, would probably be great on the track for any of us slow guys who like the bottom/mid...

    Truly are impressive work of art backed up with very good talent. Congrat's. MY 92'kdx will never look the same now, thinking on how it should be made. The high end chopper building boys have nothing on you. Good Job!

    Thanks for the comps guys!

    So I did have a chance to get out and ride this last Sunday. I can say it’s good and not so good….

    The balance of the bike is great, definitely “feels” lighter than the KDX (not sure what the weight reduction actually is), easier to ride through the technical stuff than the KTM. As I made each consecutive loop I found myself less concerned with my lines, so it would seem that the suspension is at least in the ballpark.

    With the RB carb mods, I have the 1/8-1/3 throttle bog when whacking the throttle with the bike on the flat… tried some different known setups including what RB sent without a cure at this point. On the trial when the motor is under load the bog does not exist… other than she feels just a tad lean, but even with that she would pull from virtually nothing to WOT without complaint. I would say that the head mods have really strengthened the low to mid torque, making the bike super nice in the technical stuff.

    I have some jetting to get sorted out (after hand surgery that is) and have several things to try based on what others have found.

    Currently:
    PJ = 40
    AS = 7/8 – 1.5
    Slide = #7
    NJ = JD red #5
    MJ = 152

    If I had thought of it at the time.... I should have welded a mount for this KX100 kickstand to my frame, before I powdered it that is! Just something to keep in mind for future hybrid builds.

    I compiled this as a downloadable pdf incase anyone wanted to make their own hybrid and use this as a manual. I hope that's okay with you HRDROKN, if not, I will remove it.

    It's a 9.4mb download.

    >>>http://dl.dropbox.com/u/14084841/KDX_Hybrid_by_HRDROKN.pdf<<<

    I will keep this link running as long as I can but there are no guarantees.

    Thanks for your info HRDROKN.

    New to the forum

    Awesome work on the pdf, last night I sourced a 03 125 with a seized motor and have a 97 200 motor under the work bench. Project about to start....

    A quick question - the motor has no carb. Will the 125 one suitable or is it not big enough????? If not, what carb is best for a 200

    this may be a silly question but why use the kdx engine and not just use a kx engine?, is it because the kx engine would need rebuilds more often. very nice build by the way.
