Timing Marks
The flywheel can be identified by the stamp mark in location A. Refer to "I.D." location in chart below. Do not
use the cast mark to determine flywheel application.

600/700 - - DC / CDI IGNITION
The Sportsman 600/700 has incorporated into it's
design a DC/ CDI ignition system.
Some of the advantages of DC ignition are:
Stronger, more consistent spark at
G
low rpm for better performance
Easier starts
G
Simpler component design for ease
G
trouble shooting and maintenance
NOTE:
DC/CDI systems and compo-
nents are not interchangeable
with any other system.

Operation Overview:
The DC/CDI system relies on battery power for ignition.
Instead of generating DC voltage via magnetic
induction, a 12 volt DC current is supplied directly to the
CDI unit from the battery at the CDI, 12 volt DC current
charges an internal capacitor to build up the initial
ignition charge. A small A/C signal from the Trigger
(Pulse) coil closes a thyristor (located in the CDI) at
a point pre--determined in the crankshaft rotation by
magnets on the flywheel's outer diameter. This signal
releases the electrical charge which saturates the coil
for ignition. DC/CDI systems have the ability to ignite
with as little as 6 volts of power.
