hey there, I have a 71' currently with drag headers and am thinking of getting a 4 to 2 to 1 exhaust. When I open the throttle while at highway speeds the bike sometimes bogs down a bit. I know it's probably an issue associated with rejetting the carbs. As I've heard most bikes come off the line on the lean side and once you change the exhaust it can affect performance even more. I'm wondering if anyone can suggest the size and type of jets that would work for my bike. I've had a hard time finding anything.
Thank you.
Thank you.
