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 The previous version was outdated and no longer supported.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

Help- SM610 Nasty Vibration

D

DesmosDromos

Husqvarna
C Class
On the ride home from work I got a real nasty throbbing through the whole bike at a rate of about once per second or two. I thought I had a tire issue or something pulled over and could see nothing obvious and the bike was still doing it at idle. The engine didn't sound rough or anything, so I figured I'd ride a bit and see if it got better.

It did stop the throbbing, but it seemed a lot buzzier than normal. At 5,000 RPM the pegs and bars were really vibrating and kinda uncomfortable. I got it home and when reving it on the side stand it gets a nasty rattle sound through the pipe at about 1,600 RPM and the bike visibly slides backwards a couple of inches. Idle seems normal and no louder than usual.

Any ideas? Did I break something in the silencer or is it worse than that?
 
A couple of things to check. First, check your engine mounts, expecially the top mount, this one has a tendency to come loose. Another thing to check is your crankshaft and balancer nut. This requires removal of the right side engine case. If any of these large nuts are loose, they can cause big vibrations. Also, you may need to replace the woodruff key that locate the gears that drive the counterbalancer. Good luck and let us know what the problem was.

Yeah, based on the description of my problem and the posts I've found on the counterbalance, it's gotta be that. I ordered the parts from Hall's and will deal with it when the order arrives. Thanks!
 
Someone's just posted a similar thread on SMjunkie which is probably worth having a lookover and there's also a link to a thread on ADVrider (both have pics and how to's etc.) Good luck, although it's not too big a job!
