trx250r no spark

Hi, My 1987 TRX250X has no spark. It would start intermittently and eventually quit. I took it to a mechanic and they replaced the stator. It ran for a while and has quit again and will not start. It does not have a spark. I replaced the coil but it still won't spark. Any help is appreciated.

Have you checked the wires going to the coil, could have a break in the wire.

that honestly sounds like a stator. i had a lt500r that did that. it ended up being the pickup coil on the stator. also check all the wires. when it happens unplug the wires on the stator and check the ohms

I hate electrical problems - just a poor connection (especially a poor ground) can cause chaos. Note: the coil that produces spark is pretty durable and does not fail very often. The spark plug cap goes bad more often than the coil. The typical sequence of failure is connections, the stator, CDI pickup (or pulse or trigger) coil, CDI box, plug cap, coil and (on rare occasion) the flywheel magnet or rotor. Most of the time the trigger coil cannot be replaced without replacing the stator. However, your TRX250X has a replacable "pulse" coil. Have your mechanic check it. It's about a $25 part.
