Fazer 1000 Gen 1 misfiring

[ptolemyx]

From what you say your battery seems fine. But check the connections, especially the earth and starter motor connections. Got my Fazer cheap cos previous owner was suffering from frequent flat battery which he kept on changing - turns out he had an auxiliary power outlet (cigarette lighter and usb point) permanently connected to the battery,; small residual drain from that when the bike was unused a few weeks was enough to flatten the battery.

And why do you ask about using an Optimate? Completely unnecessary imho........
