Manual Revision: 041608
*- Medium/Hard is the recommended initial setting.
Notes:
The pattern for the
24 ball setup
is
8 balls followed by 1 empty slot
Empty slots
must
be evenly spaced around the pressure plate
Engagement RPM
Low, Medium, High
Refers to the engagement
RPM
of the clutch, i.e. the RPM at which the clutch starts to engage and move the bike forward.
Low gives an engagement point at or below a normal engine idle speed. High raises the engagement point to above a
normal engine idle speed.
In general
, off-road riders prefer a low-to-medium engagement RPM, while motocross riders
prefer a medium-to-high engagement RPM.
Engagement Rate
Hard, Soft
Refers to the engagement
rate
of the clutch. Hard gives full clutch lockup more quickly than Soft and therefore makes the
bike feel more snappy. To maximize clutch plate life you should use Hard settings, as Soft settings allow the clutch to slip
more.
Important Tuning Tip: Idle setting is a
critical
component in tuning your z-Start Pro. Setting your idle speed
at or slightly above
your
Engagement RPM will yield engine braking close to stock. Setting your idle speed
below
your Engagement RPM will yield more of a freewheeling
effect.
