K&N Oil Filters BEWARE!!!

[the Ferret]

So happy I found this thread. I JUST HAD THiIS SAME EXACT SITUATION YESTERDAY. I can add photos later.

I use K&N filters on several of my bikes with no problem. I did an oil and filter change on my CB1100 2014 last month and installed the KN 204-1. On Saturday I rode up Berthoud Pass, CO fairly aggressively. On the way down my fellow riders were letting me know that my pipe was smoking and they couldn’t figure out why my tire was still ‘wet’. It had rained much earlier. We pulled over and realized I was drenched in oil. Horrifying - especially if you know that road.


I said it was probably because I only hand tightened the filter. So we cranked it down and I topped off oil. Also pursued a few burnouts in the sand on road shoulder to clean the tire.

Thought it was settled, but no. Still spewing out of this filter. Had to get towed from Winter Park back to Denver. That’s not close btw. Just happy it didn’t end up worse. Hope I didn’t do any damage to the engine.

I am switching back to OEM filters!

Yep nice road Berthoud is on. Rode it with LR and offroad last year or year before. That would be a terrible place to have oil on your rear wheel. Glad your buddies noticed and glad you weren't hurt.
