Bump-starting an F650GS twin
Any good tips? I tried and failed yesterday! Rear wheel locks. I daresay more weight on the rear will help - so do you jump on the bike 'side-saddle'? What's the best gear to use?
Thanks for any thoughts!

If battery is completely discharged, you will not be able to push start your F650GS. The fuel pump needs to have power to pressurize the fuel system in order for the engine to run.

So what do you do if you find yourself stuck in the middle of nowhere with a flat battery?

1- jump start from another vehicle
2-if no other vehicle, make tea and wait for other vehicle! 3-if no other vehicle, make tea and wait for helpful person- there is always one around 4-if all that fails- park bike out of sight, lock up, take battery with you, hitch/walk etc to nearest garage/place that either has a charger or other batteries to take juice from. I have an 8amp hour (in strong direct sunlight) solar panel - but it measures 120cms by 70cms.... - and that would take awhile to charge your battery - a little diddy panel would take a very long time to charge a bike battery. There is a military version which is a 'foldaway' but that is serious ££. There is a commercial solution by Powertraveller (if you really want to carry this extra kit) and is called the StartMonkey 200- specs: Startmonkey200 is suitable for use on batteries with up to a 650CCA and can restart this type of standard 12 volt car battery between 15 and 20 times on a full charge thanks to its High Energy Dynamic Polymer Battery. The 400 series would be too powerful. But you still might want to buy a new battery before you go IMHO

Thanks for that Bertrand!
As I am heading off to Latin America for a year in search of remote places, options 1-4 may well not work for me. I will certainly get a new battery but still... I have been pondering getting a solar charger. I'm guessing you don't need a full charge for ignition? If I had a 'travel-size' one, how long do you suppose it would take to get enough charge to start the bike?

Full charge=no but enough to turn over your engine.
How long is a piece of string? It depends on the strength of the sunlight and how many hours of strong light you have. and depends on how many amps you need to turn over your engine- (not just pressurise the fuel system) check your manual for data. Depends on the state of your battery and so on- Then you need to do some maths! If you were to leave your bike parked for a long time- a small panel (say 5watts) will trickle charge the battery but then, the chances are, the panel might get pinched.. If this is a huge concern for you- seems to me you may wish to consider buying the '200' model But it's more money & more kit- always more kit  !!!or you might want to carry a bike set of jump leads- better/cheaper and gets you to meet the locals too! And if going in search of empty places..... I would encourage you to learn about your bike as much as possible, think laterally and innovate! too many 'what if' scenarios' !! and when it comes to bm-wobble -U's... I would not go anywhere without my '911' diagnostic dongle- Takes all the head-scratching out of it- BTW can you fix a puncture? video of the '200' in action on a quad here

I guess I would only need enough amps to pressurise the fuel system if I then bump-started it....
Of course you're right about how long is a piece of string - it being solar power after all... Then again I will be near the equator mostly. I'd really like to avoid loading myself down with unnecessary kit, that's for sure. The Startmonkey200 is 660g and £90. Hmm. Risk assessment... The 911 seems like a mighty fine idea. But Touratech here in the UK want £350 for it!! And it doesn't work with either my Mac or iPhone. Bugger. I have a tubeless repair kit and a compressor but have not yet had need. After having read the drill many times I feel like I will be able to do it no problem. I will have to find myself an old tyre to practise on before I leave mind you! Your advice is much appreciated. Thanks!

Rather than buying new kit to get you out of a situation you may never find yourself in, learn how to bump start on your own.
Yes you need to jump on the bike at the point of lettig out the clutch, and I find 3rd gear the best to use. You will rapidly get knackered and overheated, so if you are wearing all your gear, take it off first. And the panniers / top box. Even unloaded you bike weighs close to 200kg, and that's a helluva lot of energy you're burning to shift it! If things are really bad, consider unplugging the headlight connectors (or removing the fuse) assuming you can't switch them off. It's not huge, but every drain on the battery should be eliminated where possible. To be honest, a new battery should last you perfectly well on a tour, and I doubt you will be out of reach for more than the life of a modern battery!

How about a scooter battery or maybe even something meant for power tools or industrial emergency lighting? So long as it's 12V it'll fire up the fuel pump (or are the electronics "smart" enough to do the "computer sez no" routine?). Probably only worth it if you are going up the Desert, jump leads and a friendly attitude are lighter.
Get the fuel pump to run and the electronics powered, bump start as you would a lower tech machine, but hit the starter button as you jump on the pegs and drop the clutch. My K100 came with a 12 year old car battery in the sidecar. As I picked it up 300 miles from home there were fuel stops, so I've had some practice! Andy

Prevention is key! I mount one of these to all my travel bikes to moniter my charging system.BikeMeters.com - Digital Voltmeters manufactured by DATEL It simply tells you how many volts you have at the battery. Go below 12 and you have a problem. With no lights or electric gear, it should read around 14.2 volts with the bike running at higher rpm, although every bike is a little different. Or you can pack a lightweight emergency spare: http://shop.testsycl.com/
I have heard of people carefully stuffing a rag soaked with gas in the airbox to get the initial hit on FI bikes until the charging system takes over, but i honestly have never tried it.

The startmonkey'200' is £149.99 but it does have an added advantage of being to charge up your notebook if you have one and all your other little electro-bits but it's $'s and weight- your call! If you do go the route of the '911' dongle, I have an unlocked Nokia E61 ready to go with the software on it I could sell you if you want cheap- Maybe a new battery and a set of bike jump leads is the cheaper way to go.

Hi Bertrand
How much do you want for the E61? I'm a bit of a 'puter geek so the 911 sorta appeals... I'm gonna do a new Lithium battery and jump leads anyway mind you! Thanks to all for the input! G
