  • It's the idea of amperage causing a problem that bothers me. If there's no problem with the bikes electrical system it will only draw as many amps as it needs. Like Lynx I can see that the voltage regulator should be roughly the same between vehicles. You're probably right about a car battery having enough cranking amps to start a bike without the car running but large twins like the r80 have big batteries because a high compression twin takes some cranking so it basically uses a car battery anyway.

  • Okay. I'm going to go away and have another think about it. My electronics is fairly basic so I might be wrong.

    However my point of, if a car battery will start it without the engine running, why risk running it; does stand.

  • I agree it should be possible from a car battery without the engine running. It's also easier to get someone to push you or even push start it yourself as long as the engine is in good running order and it just has a flat battery. Unless it has an automatic gearbox, like most scooters!
