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 The previous version was outdated and no longer supported.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

Engine Intermittently Sputters, Backfires, and then blows a fuse

Anyone have any ideas - Hubby and I went for a ride today and his bike was running great. Got up into the mountains/fog/light rain and suddenly the bike started to intermittenly cut out while at speed. A twist of the throttle seemed to clear it up. Happened again a short time later. While at lunch, his bike sat in the rain/snow for an hour or so. After lunch, the problem persisted on a more frequent basis (riding in steady rain/hail/snow), now with backfiring and he finally had to pull over. Lucky me, I got to sit in the cold rain and wait while he took my bike and fetched the truck.

Got the bike home (still raining), tried to start it - fuel pump primed but bike wouldn't start. Tried again and heard a pop - appeared to blow a fuse. Now no power at all when turn on the key.

It's a 2009 TE510 with full powerup and IMS 3 gal tank.
 
It is probably electrical-intermitant. Go over your lines and make sure all connections are firmly in place.

Agree. Take a good look under the tank at the harness, especially where wire could be pinched or passing over a sharp edge such as a bracket. Also look behind the headlight, and make sure your battery terminals are tight.

Intermittants like that are often a vibrating or pinched wire just starting to wear through the insulation. In time they will wear far enough to short, maybe blow a fuse, or become not so intermittant, but easier to find :-)
 
This is from DanBartol's 510 thread:

"Got the bike back today and the problem was an intermittent electrical contact between the coil and the spark-plug wire."
 
+1 Coil connections is a good place to look for the running problems. Coil ground connections.
Also - straightforward but check the circuit related to whatever fuse blew...
