Scooterotica

Want to go down on my carb size from 26mm to 25mm.
Will a stepped rubber do the job rather than splashing out on a new manifold or is it better to replace the lot?

I doubt that there is a stepped rubber that only reduces by 1mm thatis only half a mm a side on circumference I piece of hose would prob do it
