1987-1988 Yamaha YFM350 Moto 4 CDI Unit Ignition

 [1YW-85540-20-00 1YW21only]
1987-1988 Yamaha YFM350 Moto 4 CDI Unit Ignition

This is a new aftermarket replacement for the YFM350 Moto 4 Igniter which has been discontinued by Yamaha.

VERSION 2 DEC 2017 This is the latest version of this part. 

You will receive a new ignition coil and the CDI Unit (orange part in the photo below)

List the number that is stamped on your part in the checkout notes.

( The original part is show in the photo above)

The new replacement ignition unit larger and will mount differently than the original part. ( See below) 

This unit has some improvements over the stock unit:

  • The unit is protected against over voltage from a bad regulator rectifier,  battery, ignition coils and reversing the battery connections
  • There will be a smoother acceleration when revving the up the engine
  • This is a digital unit which is more accurate which is not affected by temperature changes
  • It has an optimized performance curve which should give you more power.
  • When the battery voltage changes this ignition unit will change the control to the ignition coil(s) so the spark power will stay the same.
  • Plug and play connectors
  • Your motorcycle should be easier to start.
  • Installation: The TCI ignition coil needs to be installed (change the original CDI ignition coil). Will need to connect the "+" side of the ignition coil to the switched 12 volt. Connect the single brown wire from the TCI-ignition coil to the brown wire from the quad using the blue wire splitting clip (provided). Connect the digital Carmo replacer also need to be connected the brown wire (same that is connected to the ignition coil) by using the blue wire splitting clips. The remaining wires are not being used, and the Carmo TCI can be connected since it is plug and play.
  • The safety interlocks for reverse is something the CDI unit does not handle, so it still works if there is an issue with that circuit
    The neutral indicator, switch and relay do operate without the CDI unit, but there is a connection to the CDI unit, just to let the CDI unit know the gearbox is in neutral. The wire is connected in the improved CDI.
