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 The previous version was outdated and no longer supported.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

sick '08 husky sm610, power drop..?

sprinting to class today on an '08 610 (fuel injected, stock but gutted exhaust, stock air filter, DIY resistor mod), and my power drops drastically. it went from torque monster to a little peppier than a scooter. pulled over about 5 seconds after it happened, throttled it, and it died. the tank was almost empty, so i rode gently to the nearest station and filled it up.

fire it up again, and it's really soft. still reading the normal rpms, just no thunder from within. i put my hand over the exhaust, and it's slow coming out. seems like low compression.

i'm going to strip it down tonight after dinner, pull the exhaust apart and make sure nothing broke loose, double-check the resistor/lambda sensor, clean the air filter and oil filter (needs it anyway). i've never worked on an engine, but i figured i could pull the case apart and see if anything looks obvious. the valves need to be checked, but i've been putting it off until graduation next week.

any advice, thoughts, suggestions on what to look for?

i'm worried, no one likes it when their baby is sick :excuseme:
 
Mine had very similar symptoms when the stock varta battery died on me. If it's very low on juice the EFI will suffer. If you still have that in there I'd check it. Mine ran the same way until the voltage was so low it began to cut out and die. My battery exploded so all this happened within a few miles for me, so the symptoms could vary. As you describe it was like a scooter for a few miles.
