    The Lectron Power Jet Carb is our go-to carb for applications like harescrambles and motocross. They are an overall upgrade to the stock carburetor as they provide superior bottom end grunt and crisper throttle response, improved fuel economy, and better reliability without having to rejet for weather or elevation changes.

     This carb kit includes the throttle cable. The adjustment tool is highly recommended in case you have to do any tuning. Using pliers to make adjustments can scratch the metering rod and alter the fuel delivery characteristics.

    *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.

    By submitting an order for a Lectron product, you are agreeing to our shipping, cancellations, and returns policy.
