High Precision Flyweights for Tuned Clutch Behaviour

Designed for .21 engines, the Serpent 903199 Centax Flyweights use precision machining to upgrade from standard molded parts. The result is a more robust weight that helps deliver reliable clutch action.

Stronger Composite Construction

These flyweights are machined from a solid piece and use carbon and graphite to produce a denser, harder component than injection molded alternatives. This construction improves wear resistance and steadies performance over time.

Fine Tuning with Secondary Screw Hole

The shape encourages outward motion for a firmer engagement rather than a trailing action. Each weight includes a secondary hole for a grub screw so you can add small adjustments to the mass and tune the clutch bite as needed.

How do I know if I need machined flyweights?

If you experience inconsistent clutch engagement or rapid wear on molded weights, upgrading to machined flyweights can offer more consistent behaviour and longer life.

Can I use the grub screw to soften engagement?

The grub screw is mainly used to add mass and increase aggression. To soften engagement, try different shoe materials or adjust springs rather than adding weight.

Do these affect idle or off-throttle behaviour?

They mainly influence how the clutch picks up under load; idle behaviour can change slightly depending on added mass, so test settings before racing.

Are there any installation checks I should do?

After fitting, check clutch shoe travel, balance, and that no grub screw protrudes into moving parts. Run a few cautious tests to confirm smooth operation.
