Any advice on carb and Air filter mods for a 1990 GSXR1100 with a Yoshimura Duplex 4 into 1 exhaust system. The bike has just been rebuilt after 25 years off the road. Fitted with standard original airbox and genuine Suzuki filter. Main jets are 122.5. Pilot jets are 40. Needle clips are in the middle and air/fuel mixture screws was 2 turns out. Doesn't run right and apparently never did. Any thoughts, suggestions gratefully recieved..
