Can you jump start a bike of a car?

Thanks,

I have done but I've always done it without the car engine running. I know you won't get the voltage you would normally get but you also can't overload the bike's electrics and it's often enough to get you started.

Yes, assuming that the bike has 12v. Like modern cars, you do have to be careful with how/when you connect the cables so as not to damage the electronics.

As above, yes you can. Do it without the car running and disconnect the jump leads as soon as the bike starts.
It'd be quicker to bump start it down a hill if you're near one or get some mates to push you smile

Yep, what I've always done too. A car battery has 4-5 times the capacity of a bike battery, sometimes more, so it will easily handle the load of a bike starter motor without the voltage dropping much, hence no need for a running engine.

I'm going to hazard a guess here Phil and say that the Falco is playing you up a bit in the cold weather, it is struggling or won't start and the dash has reset to km/h. Mine has done this over the past few days because it's pretty cold and it's very annoying. This is despite fitting a new reg/rec to charge at the best rate and the most kick ass battery I could find.

A common problem is apparently the starter relay - so I'm buying and fitting one of these this weekend to see if it helps (there's an R1 relay that's a direct replacement). There's also a mod to the dash to stop it resetting - I think it just uses a chunky capacitor to hold the dash voltage up. If your bike is like mine with a Datatool fitted, the alarm will go off if you leave it connected to a battery charger. I have an alternative solution to this which I'm going to wire this weekend - a 110Ah caravan battery, which when connected in parallel to the bike battery should stop all this nonsense.

Steve.

Bingo,

Won't start at all.

Last time I tried to jump start a bike was my old zxr-750 and it took two guys pushing to press down on the back end with me on the bike just to stop the back wheel from simply locking when I let the clutch out.

Next stop is here, to help keep the battery in top order by charging it with the right voltage. I notice you're only down the road from me, so shout up if I can lend a hand. If the thing is just turning over and won't catch you need to wind the throttle a long way open to persuade it into life. The ECU can get itself in a knot and this is the way I've found that sorts things out. I'm tempted to fit an Anderson plug in the tail to connect jump leads and make my life easier.

Haven't got a Datatool System 3 on it have you? I had a faulty immobiliser circuit on my Aprilia.

I do and I hate the thing. The meta on my sv is vastly superior, not least because it doesn't drain a battery in a week.

I have got a datatool 3 but that seems to be behaving.

Well, its going just taken it for a spin and I love it again. Just shoved the battery conditioner on and will get in the habit of doing it regularly.

Steve, whilst I can get by mechanically, I'm of no use with electrics. If you can sort the electricery out for me there will be several beers in it for you.

This weekend's a bit busy, but will let you know when I have some time free. Have a read of that link I posted as a starter for 10, there's nothing too scary in there.

Slightly off topic but hooking my Busa up(with a system 3 Datatool) to a trickle charger never caused it to go off, no matter what "mode" the alarm was in...and it doesnt with my new system 4 on the Gixer..That sounds more like an installation issue to me..

Cheers Steve, I reads that link before I bought the bike. Its the soldering that worries me.

Mines sat outside on charge at the moment and its fine

See how you go with the conditioner but I'd say a new Battery time min Phil! Mine lunched one in one year from new. I did get used to removing it from the bike for long periods of time in cold weather and sticking it on the optimate
Your falco is indeed exhibiting expect behaviour already.. see we wern't making it up wink

Steve's tip of hold the throttle wide open if the bike won't fire but just churns the starter is the best tip you'll ever get!! Saved me many many times after I was told about it.

LOL, my sodding Datatool also drained my Falco's battery. A 20 quid trickle charger from Fowlers has sorted it though smile

The battery was only changed in July. I'll shove the charger back on in the morning to see if its holding charge. If not I'm off to Halfords.
