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 The previous version was outdated and no longer supported.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

EFI FUEL TANK DRAIN??

Mehusieni

Husqvarna
A Class
How do I drain the fuel from the tank of my 510 SMR (2008)?
Or is it even necessary when removing the tank?
On the EFI models, there is no fuel cock so doesn't all the fuel leak out if I disconnect the wires and stuff?
 
That shouldn't be a problem. Think about it.

If the Fuel pump is mounted in the tank, the fuel tanks outlet hose that is connected to your EFI Throttle body is only pressurized by the fuel pump itself.

It can be disconnected and the tank removed, you shouldn't have to plug, cap or pinch off the hose at all for removal. Although it wouldn't be a bad idea if you did plug it off, just to keep debris and other crud out of the open end of the hose while its off the bike and being flushed out and cleaned.

Or that debris is likely going to be the first thing that will be in your FI units fuel injector inlet after you re-fill the tank and go to fire it up.

You probably don't want to think about that.

Thanks:thumbsup:
 
You are very welcome, Sir.

Was the bike refusing to start and run with the tank having old fuel or what?

Let us know. We all learn from these things.

Nothing like that. The bike still runs like a dream after 16000km/370h without any rebuilds. Figured I'd play it safe and change at least the piston and cam-chain. Didn't want to just rip the hoses and wires prior doing any research about the bike. Main reason why I just want to be prepared for everything, is because the garage is 200km away from me and wouldn't want to go there and get stuck 30-minutes in.:rolleyes:
 
I would tend to agree with you on that. Nobody wants to get stuck on the road let alone the open trails.

Where I live on the U.S. Border of Arizona and Agua Prieta, Mexico I ride the thousands of miles of Illegal Immigrant and Drug Cartel Smugglers foot paths going North through the Chiricahua Mountains most of the time.

Its a very dangerous place to ride but has some of the most challenging trail systems you will ever come across. You can't ignore the danger when we come across groups out on the trail. Most of my riding is with off duty US Border Patrol agents. I myself am a welding inspector for US Customs / US Dept. of Homeland Security assigned to manage this areas US Border Patrol Tactical Infrastructure and the US Border fence to oversee its maintenance and repair. The current Border fence/wall takes some heavy damage at times when it gets breached, generally caused by associates of these same groups of people we find on the trails nearly every time we are out riding.

Don't get me wrong, we do see plenty of wild animals as well but unless you want to make the mistake and go ahead and call these trails game trails, you know the majority of wild animals that use most of these trail systems are 2 legged "Drug Mules" and Human trafficking "Coyotes". Just by the Number of footprints we encounter along some of the ditches and ravines we like to ride in. The guys I ride with are expert trackers and can do this in the middle of the night in total darkness.

This can turn out to be very deadly business anytime when riding these trails and some of the guys I ride with do this same thing on the same trails working night shifts riding quads and horses for the US Border Patrol. We are not only driven by the adrenaline of the ride itself but you can never make the mistake of letting your guard down. We all have to carry a firearm like it or not. It can turn out be the most important tool you have with you as cell service is sketchy at best in some of the areas we go to.

Depending on who you come across at any given point, you may encounter individuals within these smuggling groups that will not hesitate to slit your throat if given the chance. I've seen much worse done to local ranchers patrolling their own property on ATVs just checking their water tanks for their cattle. They were found dead. This area of the State is not a place you want to have a break down or get stuck or you are very likely to be found dead yourself.

Seems like we are from two very different worlds:thinking:

All we use these bikes for in Finland is speeding and wheelies on the countryside. I sometimes go ride enduro trails with a few friends and supermoto tires. It's like having oily sex, zero traction but oh boy, it is exciting:D

Only thing we have to worry about here, is angry people who never had a moped or a motorcycle in their youth and manifest that anger to those who ride.

Stay safe.
 
What a terrible story Big Timmy. We only have to watch out for critters. I remember several years back an CH intern wrote that most of you pack when riding; guess I can appreciate why-yish!!!
 
It's still the wild west out there. The way BT described it is spot on. These cartels literally have $billions on the line in the human and dope trade. The Border Patrol is often overlooked as our first line of defense and until recently their rules of engagement with potential threats put them in extreme danger.

The job is still dangerous to be sure, but at least the catch and release program has been halted. I believe that they have been getting some sorely needed funding as well.
 
It surely is the wild west out here but like I've said a number of times before.
Who needs to wait for another holiday and stand on the curb down town to see a parade.
I can take you out on the line and head up a few of the well used trails and you can see a Freakin' Parade any day of the week, 24-7-365. Trust me.
 
We used to get illegals coming by boa,t supposed to be refugees but it cost 20k US per person to come here-hmmm!. The liberal government here (read Republican) used the Navy and Boarder Patrol to turn the boats away. The tree hugging greens and Labor (read Democrats) kicked up a stink. But guess what, no more illegals and more importantly no loss of life at sea-many died as the boats were not sea worthy and frequently sunk as it is a long way and the sea is very unpredictable up our top end. This stopped the people smuggling practice in its tracks. Indonesia was not too impressed as the illegals were illegal there too. But as they said in that great movie "Independence Day" up yours.

We are lucky here and in NZ, we have criminality of course but not to the same extent as elsewhere. Probably >95% of us do not have fire arms, the other 5% would mostly comprise police, military and farmers.
I often wonder why we do not have the same firearm culture as the US, maybe its due to being commenced as a penal colony of the UK. You wouldn't want to start a new country by giving crims firearms I guess. Also the natives here were not as numerous or aggressive as the native American Indian. The need for arms was somewhat mitigated.
I could have rifles and hand guns if needed, however the paper work, crim checks and safe stowage is very onerous. I could not walk into a gun shop or a gun show and buy weapons. Checks are very tight, any criminal record and its a no go.

That sounds like it could be fun, and educational! I can bring my own "tool" as well.
 
It has been fun, set it up with a phone call to BP and pop off a round and watch them "Quail" in all directions.
Right into the waiting hands of the BP that has swarmed them already.
Great Sport.

Yea so, I pulled the wires off like the manual said and then pulled the gas line and gas leaked everywhere, all over the bike. 2 days of non-stop wrenching and looks like I have to pull the engine out of the frame. I can take the engine apart but a torque wrench won't fit when reinstalling.

You live, you learn.
 
I don't know why the fuel pump would leak ? I have 2 fuel Injected bikes that both have tank mounted internal fuel pumps and neither of them will leak when disconnected and the tank is removed ? However like I had said before, Its a good idea to plug it to keep the open end of the hose clean and free from debris and other crud getting into the open end of the hose.

Why didn't you have a length of hose or a vacuum nipple ready to slip on the outlet fitting just in case ? Anything slipped into the end of a section of hose would have stopped the flow if it was draining. Including an old screwdriver or pencil. Or just re-connect the hose until you have something ready to go on to stop the fuel from leaking all over the bike when the tank came off.
 
I don't know why the fuel pump would leak ? ...
residual pressure when you pulled the fuel lines maybe? (which would spray for about a second, then just drip out the fuel line until empty)

Mehusieni, what problem are you trying to solve where you have to pull the motor and tear it down?

No problem. I just want to take the engine apart and have a look around and see if anything needs replacing. Changing at least the piston because the bike has a lot of hours with no rebuilds. It's winter where I live, so I can't ride it anyway.

The leaking stopped as soon as I lifted the tank and leaned it forward. Didn't really think it through.

The previous owner told me the bike has one problem. When the bike is low on fuel, fuel light comes on sooner than is suppose to and the bike bogs. He said you can wheelie the bike to a gas station but not drive it normaly so the problem is in "fuelfeeding". He mentioned something about two passages the fuel goes to the (fuel pump or injector) and the other one might be blocked.
