Most folks who ditch the stock air filter box put a small filter on the crankcase vent. The only problem you may encounter is an oily film on that part of the engine. Another alternative is to run a long hose from the vent to the rear of the bike. Little if any oil mist will travel that far. At least one guy here routed the hose to drip on the drive chain.

Does anyone know if the rubber boots were the inlet duct 1,4 part # 11015-063 or inlet duct 2,3 part # 11015-057? Also when installing these into the box, how well do they fit? It seems like they could move in and out, or is there a securing mechanism I didn't see?
At least from what I saw, you just cut a hole and fit the smaller end of the boot in and that's all (?)

Also, what is the tube at the top??
Thanks :]

Hi all,
fascinated by this mod for my KZ440 LTD & had a go yesterday, unfortunately I can't seem to get the box to go high enough as the frame stops it (only by about 1/4" or so), if the box is any smaller I wouldn't be able to fit the boots properly? (that's why there's a nice angle on the original box.....).
Have been looking at possible ways of being able to move the box back by maybe 1/2", like fitting a flange.......?

Anyone else have any ideas?
cheers
Roy

Look at second page, third post down...are your airbox holes similar to what is in the pics, up near the top?  Also, the airbox boots have a slight angle...if you have them angled the wrong way I can definitely see it making the box shift upwards.
