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 The previous version was outdated and no longer supported.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

Te449 Gas Tank Breather Valve Replacement

Mine broke and OEM replacement through motosport has been backordered for 6 weeks. Seeing if I can find a non-OEM replacement as I have nothing on there now and getting 30mi/tank when doing gnarlier stuff like hill climbs and such - suspect fuel leaks out vent line.

Anyone know of a replacement or if this is a one-way check valve, vacuum relief valve, etc?

Thank you.

Thanks! I bought a one-way valve from Amazon and installed it so air can enter but fluid can't escape. I believe this is the wrong orientation as after running the bike for 10min, considerable pressure built up in the tank and shot fuel out when I took the gas cap off. So, if I reverse it, it will allow pressurized air to escape the tank, but also allows gas to escape - my original problem of it leaking out while riding and getting 30mi/tank. However, I also believe having it installed so air/fuel goes out and nothing comes in is correct as it creates positive pressure for the fuel pump to do it's job. I have since ordered a vacuum check valve (pic below) that I think is identical to what was previously there. The difference between a standard one-way check valve and a vacuum check valve, I believe, is that there is a minimum cracking pressure to open the valve which should hopefully keep the fuel in the tank. Hopefully this will do the trick and will report back as I hate when you stumble across useful posts, but there is no ending.

You’ll see this valve is an issue on a lot of the TE 4st bikes. Most people (myself included) ditch the valve and run the hose up into the handlebars. Solves the pressure issue and bike has to be upside down for fuel to come out of it.
