Suzuki Intruder 1978 - Ignition System Maintenance

NOTE: Engine flooding may occur if the en-
richener cable free movement is less than 1/ 16 in.
(1.5 mm) .
If adjustment of the e nrichener cable is required,
loosen the lockn ut and turn the adjusting screw to
obtain the correct clearance.
Ignition System
Maintenance
Since the COl system has no mechanical parts,
there are no parts to wear out, and no scheduled
maintenance is required . If any of the COl system
components are defective, they must be replaced.
Ignition Timing Adjustment
1. Remove recoil starter. Remove the right hand
side spark
plug and install a dial indicato r in
the spark plug hole . (See Figure 2-51.)
2. Position the recoil side piston at 0.073 in. (1.86
mm) before top dead center.
3.
Check that the F mark on the flywheel aligns
with fixed mark on the magneto housing.

loosen
the four nuts securing the magneto cover to
the crankcase and shift the cover accordingly. If
the mark position is not corrected with this pro-
cedure,
replace the flywheel. After the mark is
corrected, check
the timing with a timing l ight .
4. Remove the dial indicator and replace the
spark plug and lead wire .
5.
Connect a strobe type timing l ight to the right

gency start rope on drive converter, run at
