Afternoon Men.

Has anybody actually found a set of dual air filters to fit the Mikuni BS34 carbs as I'm struggling to find an exact fit?

These are what I think are the closest but not sure if the 54mm flang ID will be big enough.

Don't want to spend 100 to find they don't

Any enlightenment would be greatly appreciated, links etc.

Surely you can just measure your carbs?

But 54mm sounds right.

I have measured my carbs and they are nearer to 56mm

Pretty sure I used 54mm filters on BS34s in the past, I don't remember them being a tight fit but I don't have the BS34s anymore, though I do have the Ram Air filters still.

Your centre to centre measurement is the most important thing, 75mm, the collars are malleable so will stretch a little to suit a slightly larger carb mouth.
