Ok guys, probably an unusual question but here goes. ***The boss of the garage claims that on the XR650L, the spark comes from the battery, and not from the engine. In other words, if i start the bike, leave it running, and disconnect the battery, the bike will shut off.*** This seems unusual, havent heard of such a thing, and implies that it would also be impossible to rolling jumpstart a xrl (whatever the term for doing that is), among other things. Anyone know the opposite? that the spark comes from the engine, and the battery is only for the electric starter? If someone with an xrl from similar year could maybe test that out if they have the chance, (ie start the bike disconnect the batt, see what happens), i would surely appreciate it. Im not looking for peoples speculation, because in my speculation also it doesnt make sense, i want real answers. Not that it matters, but the bike has been fully overhauled, inc tranny, engine.
