I'm itching to mod my carb for better performance and I think the JD/Boyesen/Zipty setup sounds good. Just need to learn about all the different aspects of this Mod cuz this will be my first time diggin into the carb on my bike. Is the FACTORY setup for my carb in Mobile, AL the same for someone in Colorado? That wouldn't make sense to me considering all what I have read. Where do I find my FACTORY info? Love the jet Dbase. That's why I want the factory specs. Need to compare leak jet and pilot jet sizes etc.
