Definition of Terms

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.
