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 The previous version was outdated and no longer supported.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

SM610 power loss after disconnecting battery

Hi, I posted this on SMJ yesterday and thought I would have a better chance at finding help, if I ask around here as well with a few additions.

I'm talking about a 2009 fuel injected model. So I accidentally dropped a couple of wrench tips and they fell between the battery and the rear fender, took the battery out, got the stuff out and put it back in place. Started the bike the next day and noticed a significant power loss when accelerating. Couldn't pull it up on 2nd, higher rpm's with lower speeds, more rattle, comfortable cruise speed with higher gears and top speed around 6-8mph lower.

Of course I can't be 100% sure it's the battery, since assumption is the mother of all fuck ups, but that's the only thing I did.

So, what gives? Did I somehow manage to disconnect/connect the battery wrong and it messed up the EFI or could this be something else?

Lambda plug has been installed to the pipe by the previous owner, and i suppose the power plug/resistor bypass thingy is in place as well (how would I know?).

Went to a dealer and their thought was that electrical issues usually aren't a common cause for power loss related problems, and that removing the battery shouldn't cause things like this. I do remember that I accidentally disconnected the RED positive cable of the battery first, and after that I checked from the manual that the BLACK ground cable should be disconnected first. While reconnecting I also did it in wrong order, ground first, then positive. Could this have caused some resistor/fuse to burn out?

I also mentioned that the bike fell on its left side while running and they thought that might've caused some issues with lubrication and/or piston rings. Even though I fell on soft sand while doing a tight turn and the bike had halted to a full stop before falling. I can see some oil leaking from the point where the exhaust is connected to the cylinder(don't know the right term, exhaust manifold?) but that was there before and they mentioned the exhaust fumes from my bike smelled a bit funny. Oil level still seems to be the same as before.

Nevertheless, they said it'd be around 500€ to investigate and that's a hefty price to pay from one small trip on sand or battery removal.

I think the oil leak and smell are just a cause of there being too much oil (window almost full), but could this relate into the power loss in any way, because the oil level has been the same for around 1500km now?

Hope you'd had the time to read. Thank you.
 
Window should be almost full ( small air bubble at top ) over fill and it will come out via vent to air filter. Not the cause of power loss. Check fuel, fuel filter, carb or FI if 08-09

BTW- check oil level with bike stright up not on stand.
