I already asked here question about alternative VR and it looks like no one here installed any another VR than the original. Ebay asks 120$ for new Buell XB VR, it is pretty expensive for such old stuff, new HD VRs are cheaper. I still does not have HD VR on hands but according the picture the HD VR wires look shorter and mounting holes in another spots. So possibly I will need to extend the wires and also build a bracket to attach the HD VR to the Buell XB.
Do you use any additional electrical accessories on your motorcycle?
