Could you show us a picture of the factory set up ?
I wonder why Yamaha didn't standardise this set up ?
I beleive that water crossing in America is about the same as water crossing in Europe.
So why the difference ?
its only available in the street legal kit not as stock on the euro/uk WR's.,,
this subject is quite an old one and has been done to death a few times !
the general consensus last time was that just routing the hose to the airbox wasnt that good as all the white goo you get from collects in the box !
as someone here has already mentioned a small T section approx 1 " down the hose (so ALL the smeg will drop out of the hose !) then a secondry hose routed to the airbox, will ensure that there is NO suck back as when the lower hose is submerged it will suck from the upper.... and if the upper hose is submerged..... you is in the Pooh !
the PCV valve was also discussed at length at I seem to recall that the opinion was expressed the the engine needs to "suck " as well as "blow" so it would in fact create negative air pressure in the crankcases.not ness a good thing !

I've cut mine down some too just so I won't accidenly kink the end of it shut.
Hmm, you could replace the hose with a balloon... : )
