...


Will these Calm Airvent Filters work okay ?

The original foam filters are long-gone.

You know..I probly should have said: "it should work". Never used those, but have something similar on something else. Guess if you can suck thru the tube and it doesn't seem restrictive...probly can call it good.

Will they still fit into the back of the air cleaner assembly with those on? I've always found it to be a pia to get those into the holes anytime I've had to take the breather off.

I've found no need to stuff them back into the holders. The mesh is dense enough to not let any turbulence in, if ya wanna let em dangle. But they do clank once in awhile. You can also just grind down the flats to fit the air cleaner holes, if need be. What I did on a buddies' bike, was to cut off the tube all the way back to the carb(s). Just enough tube to insert couple fancy (red) ones.

I did that first. Installed them coming right out
of each carb, using the short hoses. The right-side
one appeared to be - too exposed to the elements.

I haven't installed the carbs yet.

I will either grind them or wallow-out
the back of the air cleaner.

Thanks everybody.

Howdy Tim.

Welcome to VTF.

not sure which those you are meaning, tubes or black-things, but the little black things-with-filter-material-in-them can cause issues from the foam filter material breaking-down and turning into globs of plastic, clogging your carbs.
any ol' plain tubing of right size will work. there is no pressure or fear of 'air-leak' there.
they are vents to atmospheric air to keep diaphragms from "vacuum-locking" - just need 'calm (no active pressure) air to let d.s do their thing.

I don't think they are still available OEM >>> https://www.mrcycles.com/oemparts/a/yam ... 7a7/intake

Thanks for the reply Mark. I was wondering about the two, looks like added filters, In the photo below. The PO removed the MCV/AIS on my 85 xv700, and I have nothing there and am not sure if these are needed or not.

Thanks again...

sometimes I believe Yam 'over-thinks' some things - like those vents, the 'tubes' and 'filters'.
never really needed, to my mind.

Absolutely...something is needed there for the slides/jet needles to function properly. Even if ya split open the black bulbs and put some sort of foam in them. Can just glue the halves back together. But, most importantly, the tubes "have" to terminate somewhere outta turbulent air. Wanna see why? Blow into, or across them...watch the slides move, then imagine the same thing going on while riding. These are CV carbs, not mechanical. Gotta a source somewhere on the puter, for those little filters, if needed. Just have to find "where" I stored them.
