In my experience, some batteries dont last too long when you start the bike without waiting a sec for the fuel pump to pressure up. So if you start your fuel injected bike up as soon as you turn the ignition on, the votage drops across cranking voltage and fuel pump voltage thus causing current draw to increase. Its this higher current draw to that causes a battery life to be signifificantly shortened. This higher current draw also shortens your starter solinoid contacts life. harley batteries are not deep cycle so they dont like higher current draw caused by the lower crank and fuel pump voltages at start up.
Ive done this numerous times myself when in a hurry, ect and it usually costs a year in battery life. Just something to keep in mind.
good bit of info there mick44
