Thanks Bob, that is a great idea. I am going to try this on my High MPG
bike also to see what else I can do with it also

Re: Voltage Regulator

Hi to all,
If your KLR is consistently over charging your battery, I have come
up with a modification that has reduced this tendency, and applied it to
both of my motorcycles.
First, much of the overcharging of the battery is due to the fact
that the battery sense circuit (brown and white wire) extends from the
battery
source to the ignition switch, and back to the voltage regulator. This
circuit is made of tiny gauge wire, and has several contact points in it
(the
ignition switch is one), and is quite long. This results in a voltage
drop
as seen by the regulator. My bike tested out at slightly over 1/2 volt
drop. This causes the regulator to sense that the battery is 1/2 volt
lower
than it actually is, and it happily charges away as it was designed too,
trying to make up the difference.
My solution is to install a relay. The original sense line is used to
activate the coil on the relay, turning it on when the ignition is "on".
A
separate, (large gauge wire) is run from the battery positive terminal
to
the common terminal of the relay. The normally open terminal of the
relay
is now connected to the original "sense" (brown and white wire) line
going
into the regulator. This allows the regulator to sense the real battery
voltage, without the previously mentioned voltage drop. The relay acts
as a
switch, preventing the regulator from draining the battery when the bike
is
not in use.
I made this modification (several years ago) to my '83 'wing which
see's many miles at higher speeds, and it has dramatically decreased the
water loss on trips, and has increased the life of its battery! I just
recently made this modification to my '02 KLR, and expect the same
results.

Think it would pass too many solids for a clean Martini, unless you like them Dirty Martini's
