KX 500 Kits

 The 40mm is a good option applications like harescrambles, motocross, and snow bike applications for stock 500s. Modded 500s should consider stepping up to the 44HV for dunes and snow biking. Hotter bikes being used for dunes and snowbiking (525 kits with port work, drag pipes, etc.,) would benefit from the added overrev of the 44mm Standard carb.

 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 smoother 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.
