Question about 1991 Suzuki GSX 600 F (Katana)
I had a aftermarket muffler but had to change it to stock so i got duel stock mufflers now
1. vacuum leaks at the back side of the carb spigots or other vacuum lines off/broken. Remove the carbs and spigots from the head and clean with acetone/laquer thinner afterward sealing the spigots to the head with gasket maker/silicone rtv.
2. Carb idle and low speed jets may be plugged up and carbs need a correct cleaning.
3. Carbs need rejetting to match the after market mufflers. Take it to a shop with a motorcycle chassis dyno and they will be able to tune the after market pipes.

Testimonial: "Thank-you, yes had a think and bought new CZR muffler and replicated fibreglass one for the other side as a tool roll holder. Saved 7lbs."
