De-restricting a K4 600 Bandit

[Drew Vee]

Hi all,

Does anyone know how to remove the factory fitted Restrictor that comes fitted on some bikes nowadays for people who have just passed their test ?

Is it a big job or does it need done at the workshop ?

Well if it anything like what i've seen, its only a plastic washer between the carbs and the head to restrict the air flow.

So working on that take the carbs off then remove the plastic washer.
Some do have a plastic in the carbs to stop the butterfly from opening too far.

So that a look. Hope this helps.
