If I bought a Uni filter would I have to buy any type of adaptor? Or would it slip right on? Also does the vent tube press against it or would I have to rig up something for that?

I'm running the HRC kit. Would I have to change jetting? I'm in Michigan 60-80 degrees and about 700'-1800'

Thanks for any info.

It should come with everything you need, I believe it comes witha billet alumium ring. The crankcase hose should be pressed against it.

I have a UNI filter and it didn't come with the billet adaptor nor did I need one to install it.

Well, some do and some don't so I guess it doesn't matter then.

Ok cool where can I pick one up at? Is there one for the 450 or is the 400ex the same one? Is there a kit or just the filter?

I have the HRC kit will I have to make any carb adjustments.

Thanks for the replies guys.

This is off the uni web site. Looks kinda strange.

They list the trx 450r as year 98-2004

and the 400ex as year 04.

If you think you could check out the site and give me the right part number I would really owe you one.

uni filters

Hey you guy's!! The uni is a great filter, BUT be sure to use a sticky oil because the filter will let more debri in. Belray or something like that will work really well!! B)

Well Des and I are in the same state/town so I could try to help you. I am running the HRC kit minus the cam with the UNI. I am running 4th clip position on the HRC needle, a 185 main jet and the stock pilot jet. I did not need to make any changes when I put a UNI on. My jetting seems to be as close as I can get it without a dyno. I have played with it some (went to a 180, changed the needle around a little, moved the air screw around and this is where I have ended up and it is running great, starts easy, and pulls hard all the way through. Hope this helps you a little bit.

Yes that does help. Makes me wonder how much more flow you get over a stock air cleaner. I have seen a few post where people didn't have to change jetting at all either.

Do you remember where your air screw setting ended up being?

Ya I was kind of wondering the same thing as far as air flow goes. It will definitely flow better but not sure how much better because I made virtually no jetting changes...

My air screw ended up being between 2.5-3. not sure on the exact turns out because it was starting to get hot down there :lol: . I was trying to hurry up and get it dialed in before I burnt myself anymore haha.
