DerekClouser Posted August 21, 2017 Report Share Posted August 21, 2017 I believe it's the nut weld I didn't really investigate 100% yet but I will when I get home Quote Link to comment Share on other sites More sharing options...
whaler Posted August 21, 2017 Report Share Posted August 21, 2017 (edited) I think it was nut weld, but Derek did not detail. For the record I was not present, only talked to him after the incident and dig up this thread... seems like they have a serious problem on their hands.

Also was this recently installed or was there some mileage on it? Quote Link to comment Share on other sites More sharing options...

Now you all have me worried. I use the Purolator, but didn't know they changed the design. Still have some to use up, I bought them on Amazon as a six pack from the factory. Any of the recommended from that calsci list should work fine. I will avoid K&N now, I tried and didn't like their air filters either. And yes, everything Fram is terrible.

TimTheAzn Posted August 21, 2017 Report Share Posted August 21, 2017 I switched to wix and havent looked back. F K&N, not worth the risk. Quote Link to comment Share on other sites More sharing options...

what Posted August 21, 2017 Report Share Posted August 21, 2017 It was the nut weld. It split on the bottom. Derek can take pics of it later and post up... it's noticeably pushed out/burst. Quote Link to comment Share on other sites More sharing options...
jschaf Posted August 21, 2017 Report Share Posted August 21, 2017 I've been using K&N for years without problems. Just lucky I guess. Just ordered up some WIX after reading this & doing a little googling. Glad the failure today didn't cause anybody eat the assfault. Hope you didn't sustain any engine damage Derek.

2talltim Posted August 21, 2017 Report Share Posted August 21, 2017 Wonder if the failures follow a certain model number. Mine takes a 303 I would guess his gixxer takes maybe a 138. Quote Link to comment Share on other sites More sharing options...

Tonik Posted August 22, 2017 Report Share Posted August 22, 2017 And its not unique to tracks or this forum. Its reported pretty far and wide. Look, that type of failure is total BS. No other way to lool at it. 1 Quote Link to comment Share on other sites More sharing options...
JustinNck1 Posted August 22, 2017 Report Share Posted August 22, 2017 I've heard of this happening from several sources but never seen one first hand. It would be nice to know what is causing it to split. I would suspect overtightening. I'll stick with my overpriced Yamaha filter though.

I've been using these for more than a decade on all of my bikes without a single failure. No, it was done at my place in the early summer. Probably 3000 miles on it. With that being said, what is the purpose of the nut? It should take the torque as required by the manufacturer and why would a company supply and market on the fact that you can just use a 17mm socket to put on and remove.

whaler Posted August 22, 2017 Report Share Posted August 22, 2017 For the record Derek purchased, I have been well aware of the filter problems for quite some time. Have never understood saving 6 bucks on something this important. Quote Link to comment Share on other sites More sharing options...
what Posted August 22, 2017 Report Share Posted August 22, 2017 To elaborate a bit more, the failure was along the dotted red line on the bottom of the nut. Here's a handy dandy image I made: Quote Link to comment Share on other sites More sharing options...

2talltim Posted August 22, 2017 Report Share Posted August 22, 2017 Yea I've always used the nut to install and remove, BECAUSE my bike has little to no clearance to get your fingers or a filer wrench on the side. Currently have a WIX on my bike (because parts store was out of the KN) and had to dent it to get it on. Hard to explain unless you see it but you cant get any grip on it so the nut is nice.

Wolfman1 Posted August 22, 2017 Report Share Posted August 22, 2017 Always used the OEM filter and never had any issues. Sure I pay a little more, but you get what you pay for and sometimes the end result is much more costly. Quote Link to comment Share on other sites More sharing options...

Went to order one and the part number changed. Compared the new to the old and the new one felt thinner and lighter. Looking inside the bypass valve was plastic on the new part number one. On the side the old one said made in Japan the new one said made in Taiwan. And the price went up $.50. So I refuse to buy the Kawi oem filters now.

mello dude Posted August 22, 2017 Report Share Posted August 22, 2017 3 hours ago, what said: To elaborate a bit more, the failure was along the dotted red line on the bottom of the nut. Here's a handy dandy image I made: The failure is in the same spot every time. On the VFR forum, just had another guy go down cause of oil dripping out the cracked out area...... This is a class action law suit in the making... Quote Link to comment Share on other sites More sharing options...
DerekClouser Posted August 22, 2017 Report Share Posted August 22, 2017 (edited) I always just hand tighten my filters. I've never used a K&N Oil filter before and this will be my last. I'm still hopeful no damage was done to the motor. This is the result of it failing on the back stretch of Mid-Ohio at 12K RPM at ~140mph.

thompsonian Posted August 22, 2017 Report Share Posted August 22, 2017 Damn dude. Way to keep control. I too have been using K&N for years with no issues at all. Guess that's about to change and the one I have on stand by will go in the trash. Quote Link to comment Share on other sites More sharing options...

A guy in the UK had this exact same failure happen to him and it caused some pretty serious damage to his engine. K&N ended up paying for the repairs but he had to pester them for a while. If there is damage, hound them about it. Dig up purchase records, keep all evidence, etc. They HAVE been paying out and they have known about this problem for years. 1 Quote Link to comment Share on other sites More sharing options...
