CDI Replacement Services





NEW replacement CDI for Yamaha XT, AG, TTR, TT

CDI's are US made by us with US and Japan made parts. They use a
microprocessor and have the same advance curve as OEM but max
advance is improved for better performance plus has rev limiter set at 9500,
includes a ground pulse out wire (pink) for electronic tachometer.
Often these replacement CDIs do not use all wires due to much newer design.

CDI is longer than OEM and needs to be secured with zip ties.
