Dyna FS Ignition

Yamaha YFZ450 ATV

11,500 RPM LIMIT (10,750 stock)

DFS7-12P for 2004 YFZ450

Congratulations on your purchase of a Dynatek ignition. Please take a moment to read these instructions completely before

installing the ignition. The installation will only take a few minutes, but proper setup for your specific bike will take longer.

The DynaFS ignition was designed to work best with the stock coil, coil wire, plug cap, and spark plug. The increase in

spark energy from using the DynaFS ignition is enough so that adding any of these will not improve performance, and can

cause problems. Use resistor type spark plugs ONLY. Use the stock coil-on-plug ignition coil.

This kit includes: DynaFS ignition, 14” tie wrap, 8” tie wraps, Curve Selector Switch, and instruction sheets. This is a

complete kit, and includes everything needed to install the ignition.

Installation

1) Turn ignition key off. Locate the stock ignition box, it is mounted near the front of the bike, between the

headlights. OPTIONAL: To make installation easier, remove the front headlights and the front plastic ‘hood’.

2) Unplug the stock ignition, taking care not to damage the harness connectors. There is a small tab on the harness

connectors that must be pushed in to unplug them. Remove the ignition from the bike, and remove the rubber

sleeve. Keep the stock ignition in a safe place - it may be required for troubleshooting.

4) Slide the Dyna ignition into the factory rubber sleeve and then slide the sleeve to the stock ignition mounting

location. Use the 14” tie wrap around the rubber sleeve and in-between the two connectors, to secure the Dyna

ignition in the rubber sleeve. Plug the ignition connectors into the Dyna ignition, making sure the connector seals

remain in place. Plug in the Curve Selector Switch. Zip-tie any loose accessory wires to the frame.

5) Mount the Curve Selector Switch in desired location. You may want to mount it so that it is easily accessible for

initial tuning. Do not

cut or lengthen the wires!

Calibration

The Dyna FS ignition is preprogrammed with 4 timing curves. The curves are selected by the curve selector switch.

Removing the switch will cause the ignition to default to the curve in position 4(labeled STOCK on the curve switch)

which is the stock timing curve.

Curve 4 is identical to the curve that came with the stock ignition module. Due to improved microprocessor control and

significantly higher spark energy, the performance of this curve will be enhanced. A quicker throttle response and increased

power over stock is still achieved with the stock ignition curve. For the other 3 timing curves, see the attached chart for the

timing information.

Use of this ignition may require rejetting of the carburetor to supply more fuel to maximize performance gains. If you are

unsure of this tuning process, the services of a competent mechanic should be employed. Curve 4, the stock curve, is least

likely to require any sort of jetting adjustment.
