CDI systems shipped after December of 2004, have shown no
tendency to misfire or cause a kickback during start. This
includes the current Plasma III versions "A" and
"A1" and the current Plasma II Plus version
earlier Plasma CDI systems version "U3" or
"U3+", misfiring is completely avoided if the key
switch is paused for 1 second in the "Both" position
before engaging the starter. Toggle switch operated
systems have no tendency to misfire, (the issue was triggered by
the rapid "on" / "off" / "on"
sequence of the key switch motion).
other systems can be modified to eliminate any possibility of
misfiring. Contact LSE for further details.
Unmodified systems shipped before 12/04, can misfire if the
supply voltage drops below 8.5 volts repeatedly during
cranking. This can only occur if the starter draws
excessive current and the battery is not sized for that
you are using a small battery, we recommend using a wound field
starter, as they draw less than 1/2 the current of a permanent
