The 38mm Lectron is the torque monster carb for a standard BRC 500 dirt bike application. The larger 40mm Lectron retains excellent bottom end while providing better mid and top for a standard BRC 500. Moderately modded 500s should consider stepping up to the 44HV, especially for dunes and snow biking where they need a hearty mid-range but are looking for additional topend over the 40mm. Hot 500s with extensive port work looking for peak HP should consider the standard 44mm carburetor.
These kits include a throttle cable that fits the stock KTM Domino throttle. 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.
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.
