Carbs Katana 1100 tuned

[tim998]

Hi lads - existing settings: I have been told that 132 main and needle three from top is ideal for this (tuned) bike, but although acceleration is amazing, mid-range is dead and seems really flat, also I have to back off the throttle each time I change gear....  Any ideas how to lose the flat spot and cure this infuriating prob?

if it runs better backing off throttle it's prob too rich try dropping needle or smaller main
