I was wondering about the low voltage & ABS issue..
Isn't there somewhere we can place a capacitor to provide a buffer for the
ABS needs at start time?
Is it the ABS microprocessor that's choking, or the ABS machinery (i.e.,
that which modulates the brakes)?
It's the ABS computer. The problem shows up either as a result of an
improper starting sequence, or a battery that needs fixing or replacing.
It's easy to address the "bad starting sequence" problem by doing the
1 Ensure bike is in neutral, with brakes off and on level ground so it
does not roll.
2 Kill switch to ON position
3 Ignition switch to RUN position
4 Wait 5 seconds (actually, about 3 is all you need, but wait 5, just
to be safe). This gives the ABS computer time enough to boot up.
5 Engage starter button
If your ABS faults out at this point, the battery needs some care or
I don't know electronics well enough to tell you if putting in a big enough
capacitor would circumvent these symptoms, but I ask: Why bother? Is the
purpose of the capacitor to allow the rider to hit the start button a few
seconds sooner, or to mask the presence of a potentially troublesome
