Two Brothers Racing Honda TRX450R Dyna FS Ignition - Manual (Page 2)

does not fix the problem, then the problem is somewhere else on the bike. Follow the troubleshooting procedures
outlined in your owners manual.
Toubleshooting (continuted)
If the bike runs, but poorly, put the stock ignition back on the bike. If this fixes the problem, reinstall the Dyna
ignition. If you are using non stock plug wires, plug cap, ignition coil, spark plug, or stator, replace them with OEM
units. Then follow the procedures in the calibration section to set the Dyna ignition up to work with your bike. If
calibration doesn't fix the problem, the ignition should be returned for testing. If the problem persists when using the
stock ignition then the problem is external to the Dyna ignition. Follow the test procedures outlined in your bike
owners manual to pinpoint the problem.
WARNING:
Installation of a grounded tether kill switch to the ignition coil signal
will damage the CDI and void the warranty.
Magneto-CDI (Banshee/TRX250R/400EX/450R/etc.): Use a normally open tether kill switch
connected in parallel with the stock kill switch input to the ignition. When the tether is removed, it
should ground the input to the ignition.
