Oil Filters?

Update:
The dude at TR that handles this stuff has emailed me.
I replied with all the info.
He's looking into it.

I'll update again as info becomes available...

I know that the K&N filter number is a KN-141 and I thought K&N also made filters for HiFlo?
Pretty sure the correct HiFlo filter should be a HF-141...
I wonder if they made a mistake on HiFlo's website or if they changed the filter number for some reason?

UPDATE:

It seems that my inquiry has resulted in a change in the TR parts list.

Here is the page from their catalog as of today 4/13/11.

i bought a reusable stainless from moose racing and it was slightly shorter than stock. wasnt too sure about it so i ordered a different brand reusable and it didnt fit quite right either . now I use Yamaha OEM filter only on the advice of a good yamaha buddy.

"what you could lose by using the wrong filter FAR outweighs what you could gain by going to a better aftermarket filter" just use OEM is my suggestion

From what I read the Yamaha filter outfilters all the after market crap.

Does anyone know the difference between the K&N/Hiflo 141 and the 140? I've got an '09 and when I bought my first oil filter I looked in the K&N catalog. It said to use the 141 (that was about a year ago). So I used that for 2 or 3 oil changes and did not bother to look at the catalog. Now the catalog says to use a 140 for the '09 up models. I looked at the K&N website and the specs appear to be identical. Same height, same diameter, both have pressure relief valves, both don't have anti-drainback. What is weird is the 140 weighs 0.01 kg more.....and the box is a little bigger.....
Inquiring minds would like to know.....

Thanks,

Same here. I've been using the 141. The K&N catalog is fucked. I've solved it now however by using the best one made...the Yamaha filter.

ok so we have seen varrios aftermarket filter part numbers and discovered that there are different part numbers for oem filters depending on the model year.

so my question is what are the yamaha part numbers?

i would like to double check that i got the right thing from my stealer.

5D3-13440-00-00 is for all model year WR-250R and WR-250X.
That's 2008 - 2011.

I recently had a chance to buy the HiFlo 140 oil filter & took photos side by side with the Yamaha OEM filter for the WR. It appears to be very similar to the K&N in color & material. Internals were similar except for the style of metal inner support for the filter pleats. Looks like the HiFlo has more pleats also. The HiFlo was $4.60, the Yamaha was $10.95. I'm going to try the HiFlo & see how it performs. Just wanted to post this for those who wondered what these filters looked like on a side by side comparison.

After wading through this thread I went out and bought 2 Yamaha filters at $10 each.

YSP shows a new/superseded pn for filter:

5D3-13440-09-00

OK so I have been looking into the discrepancy between the K&N filter numbers. From what I can tell KN-141 was designed after Yamaha part number 5TA-13440-00 which is the original oil filter for the 2008 WR250R/X. The KN-140 is designed after the 5D3-13440-00 which is what was used in the 2009+ WR250R/X.
So I guess K&N and HI Flow just redesigned their part for the new filter specifications which may be slightly different.

I do have one question however, do the new oil filter part numbers supersede the old numbers so that if you get an oil filter for a 2008 bike will it be the same oil filter ordered for a 2009+ bike?

Been using maxima pro filters.
Under 6 bucks a piece...

Yeah the Hi Flow filters are around $5... I'll post more info when I compare a couple.

I get a few at a time From Amazon, depending on what else you are ording you can get free shipping.

I use the K&N with no real special reason.

Found some great filter on ebay. Only $2 each. I bet I can save 10 bucks this year. Sure hope I don't have to do a rebuild on the engine!

Man I would love to see some pics Im looking into a reusable filter option
