38MM High Velocity Lectron Carburetor

This kit includes a 38HV Lectron and a throttle cable. The adjustment tool is highly recommended in case you have to do any tuning. 

IF YOUR DIRT BIKE HAS A THROTTLE POSITION SENSOR simply follow the plug up to the harness and disconnect it. It is not required for use with a Lectron. It is recommended that you wrap the plug in electrical tape to prevent dirt from entering it.

*Lectrons provide superior throttle response and power delivery by utilizing our patented metering rod.

*Our simple design does not incorporate multiple jets to replace.

*Our taper bore squeezes the air to increase speed and create fuel lift behind our flat metering rod.

*Lectrons are a great choice for riders seeking performance, fuel economy, simplicity and smother power delivery.

Depending on some set ups, your air boot may rub on your shock spring. This is not an issue as the spring doesn't move enough to cause wear. 

We do not recommend running a reed spacer. They may cause fitment issues, and the longer body of the Lectron compensates for the longer intake tract.

Note: All carbs are built to order and have a 7 day build time, however, some orders will ship sooner.
