I'm curious. I've got a 2003 venture royale. Can I not just bleed the brakes like I do my car. It makes no sense to me to back bleed unless your getting a vapor lock. Gravity bleed works best for me. I'm new to this bike so I don't know about gen 1 or gen 2. Am I missing something. Also I've been told the left brake and rear brake are linked. While bleeding should I open both bleeder attached to hose bottle blocks.
