    3 years ago I sold on a lovely year-04 Rockster to buy my wonderful auto-transmission 6-speed Honda NC750. The very best bike I've owned in 45 years.

    However, I now have added a second '04 Rockster and am wondering whether to rip out the pesky OEM air box which makes splitting the bike and re-assembling it such a PITA for clutch maintenance, and replace it with the pair of UNI red-foam filter cones that I bought and never fitted to the first Rockster..

    In a post written some years ago, one rider said that fitting the twin UNI foam cones made access to the totally inadequate, fault-prone, designed-for-a-push-bike clutch slave cylinder, so much easier without that enormous black plastic bin in the way.

    There's also the question as to what to do about the crankcase fumes vent hose that permits the engine to squirt excess oil-mist into the OEM airbox.

    Could there now be any advice or comments and opinions from the gurus ?

    P.S. I never ever ride in the rain. ¿ Rain ? In Spain ?

    It has been done, but it is a losing game. The airbox is not really much of a hindrance for a bike that should get 100K miles on a clutch. Plus you will make more noise, less power and end up with a bike that doesn't like sitting or riding in the rain.

    The airbox doesn't get in the way of removing/replacing the clutch slave cylinder ?

    You only need remove the rear shock to get at the slave cylinder and remove it.

    Plus by removing the airbox you're having to do the same work you're moaning about doing... How many times do you intend having to remove the airbox while you own the bike to make it worthwhile doing :D

    Thanks for that tip Neil - removing the rear shock instead of creating space by removing the airbox. I know Esmir ( celeb0001 ) on here went to foam cones, but it seems a load of hassle to do so.
