Bike mechanic did not recommend K&N air filter?

Filter tests... note where the K&N style come

I did a search before posting this thread and didn't find that. Fantastic link there Pete!

As talked about above, less restriction = more dust, and the K&N for that test had the least restriction and most dust.

Follow the link peeps - it is a good read if you like graphs.

Well K&N have been the industry standard for high flow performance air filters for ages.

Problem with mechanics is they will push onto the customer what ever brand they have on the shelf.

I like the washable K&N filters. They get my vote.

After reading that last thread link from Pete, I'd agree if I was riding a road bike that didn't go near metal roads. It would appear that K&N make filters that have good flow performance cf OEM paper filters. But the compromise is high flow = less filterring of dust.

I've got no problems with my K&N filter. It's been on my bike for about 6,000km according to the receipt the previous owner gave me from a bike mechanic, and I can't see any obvious signs of dirt on the inside of the filter.

I've used both K&n and BMC, and even Uni-filter on road bikes. No problems with any of them, tho the uni-filter did get dirty fairly quick. I run a K&n in My 4wd with no issues either.

If a filter gets dirty quite quickly, would that not be a good thing as long as it did not block up?

Have a look at the article in Petes post above #15, you may change your mind.

On a 07 GSX1400 i had i put a BMC filter in and had it dyno'ed, 5hp less than stock, stock back in BMC on TM. ( i guess you need some ram air to get the best out of a BMC/K&N )

I have a K&N on the klr.

It is the only filter I have had that has blocked up to the point of stopping the engine running. This from clean to halfway through the Molesworth on a very dusty ride. The inside of the filter was as clean as a whistle. Never had that happen with a foam filter.

The other thing is, and it may be coincidence but the bike started using a lot of oil not long after installing the K&N. When I pulled the engine down it was very obvious that it had been dusted

Not really an answer for you but take it as an FYI.

Read it many moons ago. The fact remains that I have never had issues with them. My old 4X4 has done 300+k , the 750 had done 65 odd when I sold it (It's still going strong I believe) and both are (were) sweet as. I've never found any dirt on the wrong side of the filters.
On the 4X4, the best thing is the K&N can handle a bit of water...the paper one's couldn't...

Did you re-jet/re-map?
