I did some research, the filter can be installed either way. The owners manual didnt specify so I figured it could be, but I live out in the sticks so I wanted to know for sure before I started changing the oil - I hate havent to stop and go to town. lol
I have no reason to be dishonest, I was happy to find a site were I could ask question about honda atv's and motorcycles. I own a 400 rancher AT 2006 model, a 1981 CB750 street bike, and the odd ball in my garage is a 2007 450 King Quad automatic that I traded a 2005 400ex and some cash for. (the 400 Rancher is my wifes bike)
On a 2005 400 ex I had it only went on 1 way and was different on both ends and said this side toward engine, on the 2001 warrior i once had it only went on 1 way but didnt say anything so you had to pay attention (my brother blew his up that way), but on my old cb750 street bike the filter goes on either way and is identical on both sides. On this 2006 400 rancher AT the filter is the same on both sides but since I bought and aftermarket emigo filter I just wanted to make sure it went on either way b/c it didnt say this side toward engine but it wasnt a honda filter so I wanted to make sure.
After I posted the message on here I stopped by a honda shop in town and checked a honda filter and asked the service employees there to make sure and they said the filter can go on either direction.
Recetly I bought a disc brake kit for the 400 Rancher and after 50 miles of break in it now works great - the drums that were on the front had to be adjusted all the time - it seemed that I had to work on them every other month.
I usally use honda oil, but this time I got suzuki's oil, because I was there buying brake pads for the king quad. (thats also how I ended up with the aftermarket oil filter too) the main thing I was told was to make sure I used motorcycle/atv oil. (I dont know that it is as important in the utility bikes that I ride now but in my old motorcycle and in the previous atvs ive had (250x, 350 warrior, and 400ex) it was important because of the clutch and engine sharing the oil.
I shop mainly at the suzuki dealer b/c they r more freindly and helpful than the local honda dearler and I went to high school with one of the owners (12 years ago)
I've alway been a red rider honda guy though. The 350 warrior I ended up with in a trade and didnt have it very long and I ended up with the king quad because I had a 400ex that was in perfect shape but I wanted a ute. I couldnt sell the 400ex for a decent price because the market is flooded with them so I traded it for the KQ. so far I like the KQ real well
well worth it. Its my wifes quad and if the brakes do not work well i hear about it b/c she is a pretty good rider but had a bad wreck as a kid so she likes her brakes to work well. plus know i dont have to work on the drums anymore.
