The D-shaped Bit allows you to remove the stock air/fuel mix screw from your Honda Shadow VT600!  No more burning your hands on a hellishly hot motor or wasting hours and money trying to hunt down the world's smallest needle-nose pliers to remove the air fuel mixture screw on a single carb from a Honda Shadow VT600!

All you need is a 7mm nut driver or 7mm socket and you can use this bit to easily remove the stock mixture screw.

You may need one of these if you order a jet kit, actually, I highly recommend picking this up with your jet kit!
