Flat Battery

[fazersharp]

Meant to be reasonable day tomorrow, so thought I would take the big bike! Alas a flat battery has put a stop to that. My Aldi charger won't even try to start to charge it as its so low, 1.5 volts. It has sat for about 3 months and is possibly the original battery.


Can I jump start the bike from the car or is there too many amps for the bike system?

The alternative I guess is too bump start it, but Im not to sure how to do that, can someone give me a step by step guide?  :o
Cheers

Easier if you are on a hill as you can sit on it and roll with the clutch in and the bike in 1st or I think 2nd is better - fling out the clutch and it should start up.
Otherwise on the flat you run along the side and push it and do the same with the clutch but at the same time you jump on the bike and the bump as you jump on is I believe where the term comes from. If you dont do this then without and weight on the back wheel it will just lock the wheel and skid.
Having said that I would never attempt it like that myself, I would sit on it and get some one to push on the flat.   
But remember that if you stop and the battery is fooked then you will have do start it again the same way
