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 The previous version was outdated and no longer supported.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

Gas tank breather line

What do you do with the top line that comes off the tank. It was connected to the charcoal canister. It is apparently under pressure and is spitting out gas all over the place.:confused:
 
The outlet from the tank is below the top of the tank and will flow fuel if you top off your tank, especially while on the side stand. I believe there is a check valve in the hose near the cannister and/or it routes up higher than the tank on the stock bike, behind the headlight.

It sounds like you removed the cannistor and left the hose hanging lower than the top of the tank? Run the end higher than the tank and connect it to a length of hose that runs down the center downtube that went to the bottom of the cannister. You do not want fuel overflow dripping onto your hot exhaust header pipes.

On my aftermarket IMS I capped it off at the tank and hooked a hose to the gas gap.

What year/model are we talking about here?
 
Top to a tee and into the lower. Route it down the front of the frame and zip tie it. Should be good to go. Nothing is under pressure until the tank is in the sun and expands.
 
Thanks. Not sure what you mean by "top to a tee" but I realized that the main problem is that the line needs to go higher than the tank before it drops down, like 99% of all other dirtbikes.

What is the lower tank line for and why does it not leak? It comes off the tank and immediately turns down and runs to the underside of the engine BUT it does not leak a drop of gas. It should leak worse than the upper hose :confused:

Get yourself a "T" conector, top tube loop down to one side of tee, other side to bottom of bike, bottom breather to bottom of tee, strait out from tank. Make sence? :doh:

I'm a 510 owner so may not completely understand, but no, this does not make sense. Earlier in the thread someone stated that the lower hose is the drain for the overflow around the tank filler. The upper hose is the overflow for the tank itself. True? If so, I would think you'd want to leave the lower hose alone and route the upper hose up to a point higher than the top of the tank itself, and then to a check valve. No T fitting to tie them together. That's the only thing that makes sense to me.

True!It's just easier to route them both down.I changed my gas cap all together and it has the typical vent tube on it which works the best.Now I just plug both holes in the tank and I get more fuel in it too.
