Air filter retaining nut?

Well, I think this question must have been asked a hundred times and I think I'm not using the search feature correctly. Just got a KLR with a VERY dirty air filter. Unscrewed wing screw and removed filter. About to reinstall, and found that the wing screw is retained by a non-captured square nut INSIDE the filter. That's the nut that sits in the middle of a small plastic strut system in front of the intake screen. So how does one keep the nut in place while inserting the wing screw? I'm about to give up and use duct tape. Thank you for any help!

To the best of my knowledge nobody has ever asked that question before. As I've never looked that closely at how the filter is retained, I went out to take a gander.

That nut is captive. If you pass the bolt through the hole and thread the square nut onto the bolt you should be able to draw the nut back into a square well. That's assuming that your plastic frame is not broken in a way that prevents the nut from staying.

The nut should not fall out of the cavity. If it does you might want to try some sort of adhesive; perhaps something like Shoe Goo.

Thanks - used adhesive to hold it in place!

I ran into same issue . I spent so much time first getting the square nut into place that I could have just done valve adjustment faster. Only to realize anytime I push the wingnut it will knock out the nut on the other side. So I got myself bolt that has threads on both ends. I couldn't find metric m6 (stock size) . Will put that rod in and hold it in place with nuts on either side . Air filter is absolutely the worse design . My gs500 Suzuki had million times better design

Sorry Karamjit Singh, but if you place a nut on Top of the Black Plastic nut holder I'll bet that the foam air filter will NOT be Fully secured against the air box and will suck dirty air under the flange.

The factory uses a heated tool to 'mush' the sides of the nut holder. I use a short bolt to hold the square nut in-place & then JB Quick Weld epoxy or possibly Shoe Goo to retain the nut from both sides & allow to cure.

Tape could even work in the field, as the flame arrestor screen would keep the tape from sucking thru the carb & engine.
