  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Air filter question TE/TXC models (probably universal)

I just got a new 2013 TXC 310r. Just changed the air filter for the first time and notice there are no mounting holes on the filter housing of the intake. Most Jap bikes have the same filter with the same 3 prongs that go into the foam filter, but unlike the Jap bikes, I didn't see where the 3 prongs mount into the intake housing to help with proper positioning. You just have to "guess" that you lined it up correctly?!? Instead of the 3 prongs sinking into the holes providing an even seal, they just sit on top the metal intake frame. This leaves a slight gap between the prongs on the intake lip. If I try, I can get my finger through the outside even with the bolt tightened firmly. Is it me or does that seem kind of dumb. I would imagine under dusty conditions under WOT, dirt can easily get around the gaps. The whole point of the 3 prongs, is to hold the filter in the correct position and when you tighten down the bolt, and the prongs recess into the holes, allowing the actual filter cage to sit flush against the intake lip. On this bike, only the prongs are flush, not the entire cage itself. Even with the bolt tightened fairly snug, I can move the filter around on the lip. Why wouldn't there be 3 holes like most other bikes?

After spending $6k on this bike, I am a little worried about this design and are thinking of snapping off the 3 prongs so the actual filter cage presses firmly and evenly on the intake lip for a better seal. Any thoughts? Please either tell me I am doing something wrong or give me a good explanation why this design is OK.

To me, without the 3 prongs recessing into the filter housing, they serve no purpose to be there.
 
I just cleaned and re-assembled the air box and filter on my bike and don't have this issue. Do you have any picks to better describe? The one I have sits flush on the particulate screen.

So you don't have the 3 prongs on your filter cage or you have the holes in the intake housing? Will work on getting pics
 
The air filter and where the filter sits(metal ring) are the same shape. the filter needs to be lined up with the ring for it to seat properly.
 
The prongs are guides. They must fit inside the metal ring AND into that rubber air boot. You need to run your hand inside the box and verify all 3 prongs are inside the rubber boot and metal ring before tightening. If any prong is not in the boot, the filter is not sealed in the air box.

This is starting to make more sense. This may be my problem. The filter looks and feels 100% aligned, but there is a gap on one side, so the prong must be sitting on the ring. Kind of crappy design. They should have made it so the 3 prongs slide into individual holes as it seems like a bit of a crap shoot.
