    That's a good story, have another one?
    [​IMG]

    We've all heard the story. Boy dates many girls, and finally realizes that with beauty typically comes a lack of brains and the personality of a brick wall, with brains typically comes a lack of beauty and still no personality, with personality comes a "nice" girl, but not very smart and not much to look at. Yes, there's a million variations on the theme.

    (Leslie, if you're reading this, you've got it all xoxoxoxox)

    Similar with motorcycles. We've all owned and ridden many of them. Beautiful ones, fast ones, strong ones, agile ones, ones that will take you around the world, light ones, heavy ones, etc, etc, etc. But, not all of this in one bike.

    I've owned, Husky's, Honda's, Yamaha's, Suzuki's, Ossa's, Bultaco's, plus more and that's just the dirt bikes.

    A few years ago, I sold a 2004 Husky TC 450 and bought a BMW Dakar so that I could get in more riding and less trailering and trucking. I could leave the house at 0600, ride the slab for 30 minutes and be in the ANF or CNF and be home by noon, or in the dirt on the way to Mojave and Death VAlley, or even Baja. It just made sense. Unfortunately, I was missing something.

    Agility, beauty, performance, and a few other things. But I gained, freedom from the tow/truck, reliability, gas mileage, strength, and to a degree that most other dirt bikes will never attain, intelligent simplicity that only the Germans know how to achieve.

    So now what?

    I ride 90% dirt, rocks, hill climbs, sand washes, high speed desert and the occasional gravel road.

    I like stuff like this.

    [​IMG]

    And this.

    [​IMG]

    And for some reason.......this.

    [​IMG]

    And at times, this.

    [​IMG]

    Now before I go any further, let me say this: I don't want to own a KTM. Yes, I know they handle the dirt better right out of the box. No, I don't like Orange Kool-Aid and I don't want to drink the Jim Jones punch just because every one else does.

    Furthermore, I don't give a fuck what you think about my bike if you don't like it. I'm not trying to talk anyone into buying a BMW. I'm only posting this thread for three reasons:

    1) To piss you off and make you say stupid things that have been said a million times before and weren't even intelligent the first time.
    2) Because other FF's have asked me to detail what I've done to my bike.
    3) Because no matter what you say, and remember I've heard it all, I love my BMW Dakar and love it more with every change I make.


    So let's take care of the unpleasantries here and now. For each and every one who does not like my thread, bike, mods, attitude, dog, cat, wife, your own wife, your own life, I'm issuing a blanket :ken to each and every naysayer, nattering naybob of negativism, douche bag, negative Nelly, etc, etc, etc.

    It simple, if you don't like my bike, disapprove of my attitude, or disagree with my opinions, don't waste your time on my thread. Just unplug....OK

    Now back to the girl analogies. We all know that you can't make a beautiful dumb girl smart, right? But we all also know that with the right Dr. you can make a smart, not so well built girl, beautiful. Things like a boob job, butt lift, tummy tuck, shaving the unibrow and beating the cromagnon forehead back just a little with a blunt object. These are all worthwhile endeavors, right?

    Back to the motorcycle. Honestly, a KTM is a great bike, but I would not like to ride one across country, or even venture too far out in the desert on one by myself. And a KTM will never be as reliable as a BMW. Come on, we all know it.:hide

    [COLOR="Red"]So, here's what my goal became.[/COLOR] To take a Bull dog-looking BMW Dakar at 389lbs dry, with 9.5" of travel, and it's beefier and wider build than most German female wrestlers, and make it a 300lb Gazelle with 11.5" of travel that won't have to worry about the lion catching it, because it will just keep going and going. Think the "Energizer Gazelle"

    Now many would say, build a TT Dakar. Sorry, but I think TT products are absolute Shite!

    So, I'm going from the ground up and many variations along the way. That's what this thread will document. Plain and simple, I like to build stuff and improve stuff (yes, I know the term "improve" is a matter of opinion). I especially like to build and improve stuff that has a good strong, reliable and well designed base to start with.

    So, I started with the strip. I will post a pic of everything that I've removed tomorrow and how much it weighed. But until then, here's a few pics of where I currently am with my Dakar. :freaky

    If you have any questions or want to see something in more detail, let me know and I'll try to get some pics for you.

    Sorry, but your wife is still a better looker, but I think you need to build some molds off this before you grind it to **********.

    Hey so the blue fender and blue paint look like a perfect match in the pics. I bet it won't look this clean again.:lol3

    About time you started a build thread on this bike. :D

    Is your light/fairing bracket made purely of carbon fiber or have you got some alloy in there to.

    Could you post some more detailed pics of the fairing and mounts please.

    Great stuff, that reliable and economic Rotax engine and the well proven FI system are definitely a solid base to build on. Would be impressive if you can really get her down to 300lbs, then it would even be better than an X-Challenge. :D What's the fuel capacity with those two rear tanks?

    I am sure there are lots of us that would appreciate some insight into how you as a pro go about making composite parts from molds to layups. :clap


    Yo Mr. X-Ray vision, I think that is some twill weave kevlar...

    Currently at 6.1g's.

    My plan to get it another 15 lbs closer to 300 is to ditch the whole stock gas tank/sub frame, charcoal cannister, and the new tail tank. All together about 28lbs. It will be replaced with a Husaberg inspired tank/subframe monocoque unit that should wiegh about 12 lbs, and hold 7+ gallons.

    Something along this look. I will be doing a full start-to-finish build report on this thread when I build this part.

    And, yes you're right. Carbon/Kevlar 2x2 twill 9.9 oz. :clap

    Pure carbon/kevlar twill, at about 5 oz.

    I'll put up more detailed pics this weekend of the fairing mounting system, the airbox, movement of the oil reservoir, skidplate, and rear gas tank.

    To each their own. If this is what floats your boat then more power to you.

    Meanwhile, I will be out riding my *BLUE*KTM that starts out well below 300 pounds, already has 12" of travel in the front and 13" in the rear - off the showroom floor. I learned a long time ago that manufacturers can usually do a better job on designing the base platform of any vehicle I buy than I can, so that is where I tend to start.

    [​IMG]

    Granted, my bike doesn't do pavement well, but I don't care - I want a street legal dirt bike, not a dual sport that I have to strip and rebuild to try to make it halfway decent on the trails - and it is way more than decent on the trails. I figure that since I am spending most of my time on the trails, that is where I want the bike to be brilliant and I am willing to compromise elsewhere.

    But by all means carry on - it is interesting and fun to see what other people do to their bikes. I don't want to rain on your parade. Good luck and keep us informed. I am most interested to see whether you can break the 300 pound barrier. Break out the kevlar, the titanium and the helium - you'll need it. I am adding a bit of weight to my bike by carrying tools/etc. - I'll meet you in the middle (I think I can stay below 300 pounds though).

    An oil change and check valves every 15 to 30 hours - maybe less often if you ride as slow as I do. I personally don't consider changing the oil and checking the valves to be heavy maintenance. The rest of the maintenance is fairly standard - checking for loose bolts and such, which I do every time I prep for a ride anyway.

    The new 70 deg. engines are not high strung, they are very tractable and as tame as you want them to be (as tame as your right hand is). But they are made for enduro racing and the maint. schedules reflect that use. Don't race? Don't need as much maintenance. Changing oil is easy, I am about to find out what checking the valves is like - or you can just take it to the dealer and pay them $80 every time you need to do both.

    Much of the engine is KTM, so many parts interchange. From the cylinder up is all KTM.

    Oh, and BTW - aftermarket tanks already made can take total capacity up to almost 8 gallons. No need to make your own. Just have the wherewithal to buy them.

    But enough hijacking NOTMYBIKE's build thread. If you want to know more about my bike you can click on the link in my sig or you can go to Husaberg.org where the real experts on Hussys are.

    Well, I had a broken DR350 (total engine grenade - rod, piston, cylinder, valves - all exploded into many pieces - not sure about the crank) and I wanted to get back into riding off-road. I could have rebuilt the DR or upgraded to something better. I upgraded. I will probably keep this bike for years - I like it. I do want a Christini kit for it (none is forthcoming) so that is the only thing that might make me want a different bike if that turns out to be impossible - I am willing to wait to see if Christini ever creates a kit for the new Hussys - they are waiting on the economy to turn around, as am I (unemployed).

    Yup - $400 for the subframe tank. ~$675 for the front tank. ~$520 for the rear tank. $1600 USD for all three (maybe less - not sure about the Aqualine - the prices shown on their website are AUD and include tax - don't know what they charge for it here).

    By the way, my next project is Berg inspired. One piece gas tank and subframe.

    I can't help myself :rofl

    Thats once a fortnight for me; you don't call that high maintenance?

    I'll stick to my rotax engined Xchallenge with oil changes listed at 6k miles. Makes me feel like I am doing the bike a favour by changing it at 3k miles. :D

    At least the less BMW parts you leave on the bike,the more reliable it will be.
    Of course a stock KTM 690 will kick its ass up one side and down the other with out breaking a sweat,like you said you just like to keep busy.

    Id rather ride personally, but thats a personal issue.

    It may well work better then a DR650 when your done.
    Just dont bounce all that pretty carbon fibre off too many rocks.

    Your snotty attitude invites snotty responses,have fun in the garage.

    And no I dont give a rats ass what you think either.

    Of course I keeed,always keeeding.

    Why did you edit it? I preferred it the other way. Hopefully not to correct the spelling of "responses".
