    Is it just me but riding and wrenching since before most here got off their diapers, never really had much problems with any of them crappy carbs or crappy EFIs. I still prefer the later....so much better in cold climates.:lol3

    Looking for a big thumper right now, don't really give a shit if carbed or EFI, will just get the right spare parts if I feel they may be needed,pack up my tools and go on my merry way.:ricky

    my 81 928s ran perfectly
    no problems
    with fuel injection
    just the thirst

    ok lets discuss german fuel injection. lol

    I think the moral to the story was, don't ride a street bike in the dirt, thinking it's a dirt bike. If that was a 450 or 300 KTM, you could have just blasted through or over that. Those aren't dirt bikes, guys.

    Computers run our lives and make things so much easier. But when computers fail, which is not that often, it all comes to a stop. Technology improves our ease of doing things and I wouldn't go back. To be stuck in the middle of nowhere because "computer says no" is just the result of our reliance of technology. There is more good than bad that comes with technology. Build a bridge and get over it.

    Wroooong. My TE300 is very much carbed. Im looking forward to the day that KTM adopts direct injected 2-strokes...and hope they license the technology from polaris who's proven it... and hope they have a retrofit kit for the carbed ones. It's brand new and already I'm tired of fiddling with the goddamn jets and needles to get it to run great, which i'll just have to fiddle with again once it gets warmer. Or I go up in elevation. Or the humidity rises. And it won't drink expensive gas like it's going out of style.

    I tried to limit the list to bikes advertised by the manufacturer as "dual sport" or "adventure" - aligned with the OP question. I know you can add a light kit to many dirt bikes to get them street legal, but I was trying to keep it simple. I think a few of the carb'd Hondas listed fit into that category (bring on the corrections!!!) My bad if I miss a few...

    From their website, I don't see a Husaberg sold as a dual-sport (TE300 - "Pure Enduro"). Did I miss that one?

    I had a 1982 and a 1987 Sciroccos. Never a problem. The 81 Porsche 924 is the one that had a problem. It always started but had a miss, a flat spot at 3K RPM. Then I moved from old German cars to old Italian cars. The 1969 Alfa Romeo Berlina and the 1987 Alfa Romeo Milano. The Milano, that is the car I miss the most of all old cars I've had, with that great V-6 motor. Sold it when I moved out west in 2005. A friend of mine has the Berlina now. It still runs (in 2008 he drove it cross country, from Oregon to Ohio).

    But back to fuel injector vs carburators. There is no looking back. Except for the fun of working on them in the garage, taking the carburator out for a rebuild. The self reliance thing. That was fun. But I'm so glad now that I press the go button and the FI vehicles always start.

    Well, that one had a V-8 motor if I'm not mistaken. I whole different animal than my poor man's 924.

    The notion that “an adventure bike” will experience the same environmental extremes as a bike racing the Dakar is outlandish.

    A good example of why “adventure bikes” with FI are preferred over Carbed bikes can be read here:

    http://advrider.com/forums/showpost.php?p=20589578&postcount=941

    I own a Yamaha 125cc Lander which is carbed and a Yamaha 250cc Lander that is FI.

    The two bikes can be been parked for 3 months and the 125cc is the one that will not start. The carb needs to be removed, cleaned and constantly maintained.

    The 250cc with is FI starts in seconds regardless of how long it sits there and has never had a problem with starting or the injectors.

    I will never buy a bike with a carburetor again.

    Haha no, you didn't. you just said ALL KTM's but i suppose it depends on ones definiton of 'all'. Anyway my point was that I'm a fan of FI, and really don't see any advantages to carbs over FI anymore these days. the FI system on my SV1k has been working flawlessly for 7 years now. Theres really no reason that the euro enduro makers shouldn't start going to DI for their 2-smokes, since the sled companies have been doing it for a few years and it's proven to work. Increase power, decrease fuel consumption and emissions, and most importantly, perfect 'jetting' all the time. Pleeease KTM do this, and make a retrofit kit available!

    I guess I'm not against EFI, but if it's on an Adventure-marketed bike, it should surely be built in to have all critical pieces of it built in and protected enough that it isn't getting hurt when the bike is dropped. I guess this is an area I've really never thought of carbs as superior, or even thought of them at all - in my experience, it's non-existent to have carb damage due to a get-off that would prevent the bike from running correctly. Other things may be damaged, but the fuel system in a carbed adventure bike doesn't seem a concern.

    Tree branches reaching in and yanking on carb parts just isn't usually a concern with a single central carb during a lay-down / get-off. I haven't studied how protected most single-cylider EFI systems are on modern MX bikes, but surely they're not fragile?

    It only takes a minute to shut the fuel off, run it until it quits, then drain the last drops out of the float bowl. It's not the carburetor's fault.

    It clearly says dual sport at the top of the post you quoted. :asshat

    reading comprehension owns you.

    true but same fuel injection i think.

    just chipped my diesel grande cherokee jeep, $120, plug and play

    still will take it out in the bush,

    spent too much of my life trying to jet my bikes.

    one mistake and a hole in the piston.

    probably would not have happened on fi bikes

    i remember when in the 70's

    the worry about electronic ignition

    still waitng for one of mine to go wrong

    cheers

    I feel the same way about radiators, plus they add weight up high.
    Then you have to add guards and shields and can still bust one.

    Both of my current bikes have radiators. The weight is of no concern, they only hold about a pint or two of coolant, and the radiators are both aluminum. No issues, ever, on any of the watercooled bikes I've owned, and there have been a lot.

    Yes, of course, but it only takes me a second to turn the ignition off, it is not FI's fault :D

    Yes... yes it does. And yes I am. Regardless, FI is the way of the present. Can't really blame the snapped off fuel injector on that BMW on the fundamentals of the system, just... erm.. 'curious' German engineering.

    put something on and stay in that position.
    First of all, the fuel injector plug on the BMW didn't break. It went on the German Holiday.

    Secondly, I have never, ever had any issues on any FI bikes I've ever owned, say, 135,000 miles? Even the rudimentary FI system on the F650 is bomber and never let me down regardless of what crap fuel I was forced to buy.

    Although I don't have one, I did use my 1998 XR400 to tow a WR426 out of Evart with a broken and leaking radiator. I have no idea how thin the oil in the XR was by the time we made it back to the truck, but it was damn hot.

    I have guards for the F650 Dakar somewhere but I can't be arse to fit them. Didn't stop me riding 1,000 miles of gravel last summer.

    I have no need for rad guards on the 1150 GS or the XR.

    I have no need for a battery on the XR400. I suppose, by some of the postings here the XR400 is the optimal adventure bike. No FI to fail, no battery to go tits up with a dead short, and no rads to break.
    That being said the new BMW 1200 GS is watercooled and gave me morning wood.
