Specs At A Glance

Good To Know

Q: Is this set compatible with my ATC250R or ATC250SX? A: It is listed for the 1986 ATC250R and 1986-1987 ATC250SX, but wiring and connector changes can occur, so check your machine's ignition setup before ordering.

Q: Should the coil and CDI both be replaced? A: When ignition symptoms are unclear, replacing the coil and AC CDI together helps rule out either part as the cause of weak or missing spark.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
