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 The previous version was outdated and no longer supported.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

2013 TE511 fuel tanks not communicating

The low fuel light is on and the rear fuel tank is full - both fuel petcocks are open, but the fuel is not moving to the lower fuel tank. Bike is still running fine, up to 37km total so far, no modifications, evap can still on.
Blocked hose maybe? Anyone else experience this?
 
I have seen the vent line plugged before. Make sure they are not kinked either and the one way valve is working.

Sorry I snapped a pic , uploaded it to photo bucket and pasted a link to it while running late for work... The vent line that comes off the left side of gas cap , it ties into the EFI tank. If this line kinks or plugs it will not allow fuel to manifold into the EFI tank. Fuel will only go into the lower tank at the rate the engine consumes fuel
 
:thumbsup: If you say so, I see something entirely different, not sure what, but it aint no gas tank!
 
Thanks guys, I will start looking for kinks and tight zip-ties. It's nice to know which end to start at when there are so many:) kinda reminds me of that old "pipes" screen saver;) if I see a specific spot I will try and get a photo of it - Ciao
 
Update from Vegas, took off evaporative can, plugged hole back into intake on engine, un-pinched left side vent hose from lower tank, took of 2 way valve from right side vent hose & replaced with one way valve and routed to the gound - test rode last evening - all systems go! Just a note when I took off the 2 way valve (looks like little flying saucer) it had fuel in it. My theory is: enough fuel was trapped in the line that it wouldn't allow air into the upper tank and that there wasn't enough fuel to meet the "threshold" release point of the valve to allow the fuel to drain out of the line.
I'm still trying to come to gripps with the fact that all the emmissions requirements put on can be so detrimental to the normal operation of the engine. It just seems so counter productive when an tuned engine is most efficient. It's very similar to the filtering requirements of diesel engines it requires more diesel to push the exhaust through and re-gen etc, from driving from point a to point b. I don't know, but I guess someone has calculated that there is a net gain for the environment???...
anyway, better go riding:)
 
I will reinstall the two way tomorrow - I might try to position it closer to the vent outlet on the tank.
Had a fun day at Nelson hills today though -)

Kind of like the performance of California Government?
 
When you remove the tank vent line from the charcoal canister, most people reroute it to the bottom of the frame. This allows dirt to find its way up through the vent line and we have seen plugging. Also gas fumes on a hot day can be found coming up from the line. A simple solution is to install a vent nipple to the back side of the air box and attach the vent line there.

Be aware that in some situations you can get raw fuel out of the vent line.
 
Sometimes when it is really hot out, the gas from the vent line used to make me a little dizzy. I don't smell it anymore.
