Hello all, I’ve seen a few post on here with the similar questions, I just finished putting together a 1979 GS750 and took it out for my first few rides, runs good at low speeds, mid range breaks up a tone and is barely drivable and one you dig through the mid range it lights up and pulls great at high range. The guy I bought it from build a set of headers that are baffled inside and dump straight down from the exhaust ports to the ground (comes out the front of the motor turns down into two separate two to one headers and dumps straight down) no mid pipes of muffler. The bike also has pod filters. I’m dreading the fact that I will be battling air to fuel and jetting issues moving forward. Carbs are clean. Any thoughts on the best way forward. I haven’t touched any tuning yet as I’m reading others issues with different exhaust and carb filter issues
