  • 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 The previous version was outdated and no longer supported.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!

Thanks to all those who posted suggestion on how to bomb proof my 2011 WR300.

I have attached some photos of how I tackled the relocation of the crankcase breather and the top carburetor breathers. I couldn't find any photos to help me do it, that's why I took these.

I decided to re-rout them into the air box at a cost of a about $25 for extra hose and fittings.

I used two of these and a t-fitting.

I thought the top left hand side of the air box was probably the preferred entry point for the breathers. I did mount them a little too close to the ring that seats the air filter.

I positioned the fittings upwards to stop water running straight into the crankcase (I don't plan on testing it out in a deep hole)

Both case and carb breathers fitted, I also used a little sikaflex around the thread and nuts.

The tee fitting used to connect the two top carb breathers into a single fitting air box fitting.


Hope this helps others. Feel free to point out possible problems with this set up.

Cheers!

Thanks! I was going to just cable tie them under the seat. But the space is already taken up with a spare clutch and break lever tied to the frame.
Cheers
 
curious if any oil will get in your air box form the crank case breather? On my 06 I ran it up under the tank and back down and it still puked a bit of oil on hard MX tracks. Let me know how it works for you.

Yeah will do! Doing a few more mods before next ride so it will be a little while.
 
For the carb breathers i just used a pc vent kit. But id like to see more on how you guys vent the crankcase breather.
 
I ran mine up and over the rear shock looped the hose and then back down out the bottom to make the oil have a long path to travel before it can get out.
