    As long as the bike will start on the side of a hill with a dead battery, I have no problem with fuel injection or electric start on an adventure bike...:huh

    How did you get in the side of a hill with a dead battery? :dunno

    By the way, how are we defining "adventure bike" in these discussions?

    My definition of an adventure bike would be something capable of reasonably comfortable long distance touring, and some medium duty off road/dirt roads. Certainly not something like a DRZ.

    I know, some of you hard asses "can" ride long distances on them, but very very few would or do.

    I used to use my XL600R, and traveled around fully loaded (the bike, not me). I never thought about battery issues until I took a friend of mine out into the forest. He was new to his electric start KLR. Climbing out of a canyon on a nasty road, he kept stalling the motor on rocky steps. He was using the starter every 5 feet, and I could hear the battery going. I advised him to just let it idle a few minutes to let the battery recharge. In a pinch, we could point it back downhill and push start it, but we wouldn't have that option with fuel injection.

    Because of that, I would be leery of taking an injected bike very far into the wilds by myself. Now I used my Aprilia for road and light forest roads, and the XL (with drastically lowered gearing) for the nasty stuff close to home. Top speed on the XL is now about 70, so it works out fine.

    Do those of you who travel across Africa or whatnot with injected bikes carry a solar charger?

    Sounds like your friend isn't too bright, or he was in over his head.

    Honestly, there are so many ways that a bike can break that are not fixable in the rough that FI is the last thing that worries me, batteries too.

    I could give a long list of more likely items that you could break that would leave you stranded that are more likely to be an issue than batteries and FI.

    PS 70mph on a thumper flat out removes it from my list of Adventure Bikes! Freeway riding would be a bitch on it.

    He was in over his head, but I have to take some responsibility for that. I misjudged a few things: his ability, the weight of the bike compared to my XL600, and the condition of the road. He ended up crashing into a rock wall, and his wife (at the time) said I tried to kill him. :shog

    He is now engaged to a Roller Derby girl, and still wants to go riding with me, so all is good! :clap

    Whether it could be bumped on a discharged but not-completely-dead battery would depend on the fuel injection.

    No.

    Unless you have a very large (think many square yards!) it will not have the capability of restoring a faulty battery (not enough current capability).

    If the battery is not faulty and has a little charge in it (above say 12 volts open circuit) then you could use a small solar charger .. but it would take many HOURs to recharge the battery...

    Better than a solar charger is an other battery and some jumper cables. Make some to fit your bike before you leave!

    The above apply for any engine that requires a battery to start, not just EFI, electronic ignition etc.

    -------------------
    I know someone who rode with a set of charging wires between bikes - the battery was that faulty. :eek1

    Make your leads long ones?

    ...first hand experience, this morning.

    Marion, MA
    35 degrees
    Bikes have been sitting in the unheated garage for 6+ days (Huskys)-2 weeks
    2001 Triumph Tiger 955 (with borderline head gasket) EFI...fired right up
    2009 Husky TE450 EFI...fired right up
    2012 Husky TE250 EFI...fired right up
    2006 Yamaha TTR 125...no start
    2005 Honda XR50...fired up second kick
    1999 Suzuki DR 350 (441 kit and pumper carb)...no start

    Yay, you can work on carbs on the side of the road. Good fuckin thing, cause you'll need to :baldy

    Hey carb lovers/EFU haters... :fyyff

    Hi all ! It is proven that a properly jetted carb makes more total power than the same engine with fuel injection . What the fuel injection does better is better starting, better fuel mileage and better part throttle response . When I read the forum posts regarding mapping and trying to load different FI setups for pipes and other engine mods it makes me love my carbs . Also, with carbs is I don't have to depend on someone else when something goes wrong . To each his own I suppose .

    Proven? Really?

    You mean a properly jetted carb makes more power than an economy/emissions tuned EFI. A properly tuned EFI system will do better than any carb. Depending on the bike, tuning the EFI may be easier or harder than setting up a carb and on some particularly highly tuned machines, the power curve with a carb may look like an EKG trace.

    Dude, he said Proven. That settles it, debate's over, give up before you embarrass yourself further :deal


    You would if you didn't know anything about carbs. Somebody who is willfully ignorant of carbs and refuses to learn anything about them will need help when something goes wrong.

    Serious question (as in, not being a smart ass), You can't pop the clutch on an EFI with a dead battery?

    (not trying to be a smart ass, I have never actually tried it so I am speaking out of ignorance. I have popped the clutch on several cars and bikes to get them started. I couldn't get my V-Strom started by popping the clutch (it would burble and gurgle, trying to start) but I figured it was because I wasn't going fast enough)

    It all depends on the bike. A dead battery on most electronic :dealignitions means a no start as well.

    food for thought. my 99 fuel injected 900ss got mid 40s fuel mileage. my 98 900ss with huge fcr 41s gets 60 mpg plus. the 98 has never once dropped into the 40s. i have ridden the carbed model from 4000 ft to 12000ft . i never touch them.

    Hi all ! yes , a carb will make more peak power than a properly tuned EFI setup . Has something to do with the way a carb emulsifies the fuel versus the way EFI sprays it. Ask any professional engine builder with a dyno and they will tell you the same thing . When I was finishing my 1969 Dart ( with a 416 stroker motor) I did lots of research about adding one of the aftermarket EFI setups . Do to the fact that EFI costs much more money and the proper carb makes more peak power I opted for a Quickfuel 750 . Sorry it's not what you EFI guys want to hear but that is where my research led me . Do your own research .....it may lead you in a different direction .

    I'd take FI any day when ADV riding out west and having huge elevation/temp changes.

    Carbs like dirt better? It does not take much to clog pilot jets and such.
    You still need to filter your gas either way or you're taking apart the bike.

    An inline fuel line filter for carbs
    or something like this for FI http://www.crfstuff.com/spfufiforktm.html

    That's a funny point people bring up about dead batteries and FI.

    If you're getting to that point in the batteries life, that is the owners fault for not maintaining the bike by switching out the battery when the life is getting towards the end. You know the rules going in that the bike needs a good battery to start and run.

    If you've got years on a battery and it starts sounding questionable (at first start) buy a new battery. Yes batteries can go bad quickly but modern batteries give a warning when you first start the bike before the ride. If you can't hear that slower starting coming on (and saying I need a new battery right now) then maybe you are not qualified enough mechanically to ride in remote areas or you're just lazy.

    Deka AGM batteries are $60 a pop and always give at least 3+ yrs of solid service. Is $20 a year not in the budget to start the bike every time??? Deka AGMs are rock solid in reliability.

    Yes some batteries do, on a rare occasion, fail flat out and quickly. That can happen to any part however of any bike...it's rare and should not be a reason to say no to FI. If that's the fear buy a bike with points.
