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 The previous version was outdated and no longer supported.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

2008 TE510 Engine Died

Husqvarna
A Class
Out of the clear blue sky, my bike engine backfired and died the other day just riding some gravel roads. One minute runs great then bam. Turns over fine. Feels like it has good compression. I am not suspecting major mechanical damage, like dropped valve, blown head gasket etc. I can hear the fuel pump start up as well, and the gas tank is near full. Will not catch at all. Bike has less than 60 hours on it. Tested for spark by pulling plug, reconnecting and grounding to engine case, and it has spark. No overheating issues as I wasn't riding hard and it was cool out. I know from this board to look for damage to wiring (short circuits), but beyond that don't know where to start. Are there some likely culprits I should look for first? I searched the 4 stroke boards and didn't find anything directly like my case. Thank you,
 
Are all the fuses good. Battery cable arcing on the frame, seat cracked the battery housing, ECM harness plugged in all the way, factory bulb bad?
 
Definitely replace ALL fuses with auto fuses (mini).

Double check that there is in fact coolant in the rads.

Crank it and open the throttle while you are cranking it, be sure and be ready to hit the kill button in case it races to redline.

Grab the throttle body with both hands and act like you want to twist it out of the intake manifold, watch for cracks opening up along the rubber manifold.
 
Thanks guys. Went through the procedures you described last night. Those issues check out OK. Now no spark, and it's not the plug. I have determined that. There is fuel delivery, you can smell that. There was some sort of spark the other day, but it was likely not good spark, and helped by the fact that the engine turns over so easily with the plug grounded to the engine case vs. screwed into the head. My issue is likely an electrical gremlin in the ignition. Good threads on this board about diagnosing those (coil, stator, etc.). Now I just need to study those and see what I can figure out
 
Open up the stator cover,check for damage and clean out metal debris. File down the frame grounds. Open all wire connectors, check for corrosion and replace fuses like OHR said.
 
Unplug the connector that goes to the headlight, too many reports of headlight bulbs shorting out, that needs to be taken out of the equation.
 
Also check to see if flywheel key if equipped sheared or if not equipped check to ensure it did not lose orientation when it backfired
 
Search my threads. I had a no spark on my 07 and ended up learning a great amount about all electricsl parys and subsystems. Mine ended up being the pick up coil inside the stator cover. PM me and I can go into specifics of evetything I checkd, but most of it is documentrd in my threads
