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 The previous version was outdated and no longer supported.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

Husqvarna SM510 '08 - Fuel starvation / bad fuel pump?

Hi guys,

I had a problem with my bike earlier, i couldn't get it to start and run properly after i ran out of gas.. After replacing the fuel filter and new spark plug it ran great again for approx. 70 miles. Suddenly it starts bogging and cutting out after the bike is running hot, it then is hard to start but after cool down it's all good again (until the bike's bit hotter again).. I checked the fuel pump but nothing seems to catch an eye. When the bike cuts out i can clearly hear the fuel pump priming, even when i want to start it again i can clearly hear it prime..
But i checked the spark plug and it's dry after multiple attempts of starting the bike.

I swapped a friend's tank and the bike seemed to run fine without any problem so the problem must be in that area..

I red about some people mentioning the pump gets filled with dirt inside and it expands when hot so the bike would bog / stall but if it's that case, would i still hear the fuel pump prime?

I just would like to hear some opinions before ordering the CA-cycleworks aftermarket fuel pump.. With shipping to Belgium it would cost me approx. $180 USD so i thought it's worth asking you guys :)!

Thanks alot, appreciate the support!
 
Most likely the fuel pump, get it hot and stalling and then switch the bike off and on and listens to the pump as it primes, if it sounds lower in tone or it sounds labored or slow, it's a bad pump.
 
Well, i tried to listen each time after it stalled but didn't really noticed any difference.. Anyways, the pump is on its way from CA Cycleworks! Hopefully it arrives soon so i can finally get my bike running again as it should.
 
You said you ran it for 70 miles... that's about how long of a run I get on my EFI SMR bikes before I start to get too low on fuel. It's not that you don't have enough fuel to power the bike, but you don't have enough fuel to cool the in-tank pump. If you are letting the fuel get that low while doing some "sporty riding", you will be completely unsubmerging the pump and it will overheat. I carry MSR fuel canisters in a backpack for just this reason. Fill the tank every time you stop.
