[ben998]

Thanks for the thought but the OE air filters are still in the intake tubes, they should hopefully stop any rubbish getting in. I dont have any other filters installed.
I'll have a look though and speak to the dealers when I get the bike back - see next post!

I guess that removing them also "frees up" volume in the airbox which should have a similar effect to increasing the size of the box by 1l or so. The effects as I understand of a bigger box is to lower the helmholtz resonance and hence boost mid range.

I have heard the counter argument that installing an in tank filter takes up volume, increasing the frequency of resonance, so the opposite should apply when removing the blocks

how do you remove the restrictors?

Do a search on the old boards.Loads of threads on the subject.

Dead simple although quite a pain ... You undo all the little screws holding the air tubes and plit them in 2. Then you can remove the filters.

One thing though, be patient and use a good screw driver, those screws are a pain to remove and if you start rounding one up you are buggered!

"if you start rounding one up you are buggered!" technical term that Phillipe??
