GY6 150cc Ignition Troubleshooting Guide: No Spark?

The parts of this kit aren't returnable individually. We offer all of these items separately if you just need one or more!

Solid tested parts


There are cheap copies of copies everywhere online. Every component in this kit has been tested to be the best and most reliable version from proven manufacturers. Check out our ignition components in action!



NO REV LIMIT


We tested this CDI with an oscilloscope and trigger simulator, and found that it can produce stable spark to 30,000 (thirty thousand!) RPM. Of course, your engine safely tops out at around 11,000RPM. No limiter is needed, or exists.



Standard coil location


This coil installs at the standard location for most 150's, mounted on the side of the engine case.

Certain 150cc models have their stock coil located inside of the electrical box. We recommend against this due to the coil wire needing to be extra long to reach. This causes less spark at the plug, and ultimately a less reliable ride.

Our coils are the shorter most common version of the coil. If you have the longer version of the coil, you'll need bolt #122 to mount our coil.
