If the engine runs only on choke and does not show reaction on throttle twist,
the vacuum rubbers ontop of the sliders have holes or cuts. There are slider/rubber combos available from aftermarket companies, but it will be cheaper to buy a used carb off an XV 750, 920 or TR1 (1981-1984). They all have the same carbs.
Or you invest 600$ in a KJS single-carb system. Contains new Mikuni carb, filter and manifold. The bike runs on idle like a Harley, carb is easier to tune on different exhaust systems.
