K&N Motorcycle Oil Filter: High Performance, Premium, Designed to be used with Synthetic or Conventional Oils: Fits Select Kawasaki Vehicles, KN-401 , black

The 'O' rings that come with the filter are the incorrect size, as follows: The seal's diameter is far too large to fit in the engine casting or the thru bolt that holds the by-pass valve. pass. This created a time-consuming issue because removing the old filter necessitated the purchase of new 'O' rings; otherwise, an oil leak could occur. The new 'O' rings that had been provided could not be used. A 1999 Kawasaki 1100 engine was the subject of the application - This filter is applicable, according to the website reference. The filter itself was a perfect match, but the 'O' rings, which are crucial for leak prevention, were not. I had to re-use the old seals and was now in the process of locating the two correct 'O' rings. The problem is the material's diameter, which should not be confused with the two seals' major diameters. The new seals were too large to fit into the groove - a long way off - I'll give it my all. I'm sure there would have been a major leak if I had tried to use them. in an unexpected way It's possible that something unexpected will happen on the road.

Excellent oil filter of excellent quality. K& N has a bad reputation for failures, but the majority of them are screw-on types with a safety wire nut on the end that tend to break off due to poor welding. The O- Rings with screw-on types have been reported to fail as well, but about half of those failures are likely due to installer error. This is an internal filter, while the O- is an external filter. Because the ring isn't included, there are only a few potential points of failure.

I'm not sure why finding a filter that fits one million Kawasaki motorcycles is so difficult. A K was required to be purchased. There was no other option but to use the N filter. My motor hasn't seized yet, so I assume it's working. It wasn't any less expensive than buying one in a store, but there aren't any in the stores.

These filters fit my '82 KZ440 and '05 Ninja 250, both of which are Kawasakis. I used HiFloFiltro filters in both, based on the fact that they were once K's contractors. In the '82 KZ440, I had no problems with them, but when I first started the '05 Ninja 250, I had the dreaded cold low oil pressure issue. While this was not a major concern for me after warming up and driving down the road in the Ninja, it was still something to consider. I'll only use K for extra peace of mind. N for that bike, which has a cult following and a solid reputation. I'm comfortable extending them every two oil changes, and it's never caused me any problems.

To get the bottom plate over the o-ring, I had to exert a significant amount of force. The ring on the stem was too big and didn't fit properly, and the big one on the plate was too fat and didn't fit properly. I spilled about a half gallon of oil and had to re-do the entire oil change using the proper o-rings. rings. It didn't leak in the garage, but it did leak when the engine was running under pressure. K is something I've done before. N had never had any issues in the past, but they blew it this time.

I bought this part for my Kawasaki ZZR 1200 from 2003. I compared the new part to the old one, and the dimensions were identical. There was one minor flaw: a drop of the glue used to bond the filter material to the metal outside had stuck to the metal, but I was able to scrape it off with a knife. The part arrived quickly, and I was able to install it without difficulty. I'd buy it again if I had the opportunity.

The filter is perfect, but be aware that the O-ring is not included. The rings don't quite fit. I have a Ninja 250r, and the website said it was compatible, but the O-ring is broken. The rings are too big for me. They're far too big to be put to good use. I made use of my trusty O- I'm keeping the ring for now, but I'll try to find something else for next time. I wouldn't recommend this if you need or want the o-ring. rings.

401 o- rings. I've used this exact filter kit three times now, and I was concerned about the reviews when I first bought it on Amazon. On the Ninja 250R (pre-2008), I can confidently state that this filter and O-ring are effective. Rings fit snugly and comfortably, and I've never had a problem with getting the o- I've never had a problem with leaking rings in the past. br>br>Perhaps it's different for other bikes, but it works perfectly for mine.
