This screw is a replacement for the choke plate screws on both the Honda CBX and Honda CB series DOHC and many other Keihin VB series carbs. Use a thread locker adhesive when using these screws to avoid them working loose.
Order 8 off for the 4 cylinder. Order 12 off for the 6 cylinder
They come as standard in the professional rebuild kits but now can be ordered separately.
