The 30mm is the recommended carb for all 85-112cc dirt bikes, and the 30mm High Velocity for the 65cc dirt bikes. Each carburetor uses the stock throttle and cable.

The adjustment tool is highly recommended in case you have to do any tuning. 

*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. 

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