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 The previous version was outdated and no longer supported.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

610 counterbalancer vibrations

Husqvarna
AA Class
This is the first single I've owned and am going through a migration process regards the bikes characteristics. Read all about the counterbalancer issue and tried checking mine earlier but couldn't get the lock washer flattened out and i didn't want to risk destroying it. Tried a socket on it anyway and it wouldn't budge leading me to think it's probably ok. But... I've done a vid anyway to see if anyone that has had the problem notices anything similar regards noises etc. Be great to hear some feedback...

what happened to your right side case cover? almost a rubbing/scraping sound? definitely a little noisy, but both of mine are too.
 
hmmmm i can't hear the rubbing sound. there's a ticking sound of what i'm assuming is the valve train and the rear disc ratlles from the vibes, could it be that you're hearing? this was at about 3-3500 rpm.

i'm paranoid as i can feel vibration through my bars and pegs and anyone that talks about doing their counterbalancer nut make it sound like their bikes don't vibrate at all afterwards. but surely an almost 600cc single will vibrate, right??
 
These bike are pretty smooth..... no doubt you need to get into the woodruff key. Even if you get the nut off the key will still look ok, they shear on the inside. The vibration comes and goes because the shaft will come around and hook on the key for a few seconds and stop vibrating, then spin around and start again. So hear you go... I use a suitable drift to tap the washer back a little, then put the socket on the nut and finish tapping it back flat. Buy the proper socket period. the use a 1/2" drive air impact driver and take the nut off, I even took the clutch off. Take off the gears, get the broken key out, go to the hardware store, get the next bigger key, and file it to fit exact. The factory and replacement hardware store keys are to sloppy, so I file the bigger one to fit snug. Line up the marks, put it back together, make sure the threads on the shaft and the nut are dead clean. Apply some "RED" locktite to the threads and put it back together with the impact gun. Let it hammer good a few times, bend the lockwasher over in a new spot, button her up and hit the track.


Good luck and have fun....
 
thanks for your reply fella. this is the thing, the vibes i've got don't come and go, they're permanent. i'm inclined to think it's normal SM vibes but i won't know til i take it all apart properly, was a bit half assed with it yesterday. will order some more oil and have another look. thing is i don't have any trouble shifting which is another symptom right? blipping the throttle or sustained application will not move it on the side stand either (from vibration)...
 
If the key was sheared there would be no doubt****************************************!! It would shake so bad it would blurr your vision to ride it**************************************** If the key was completly gone, the vibration would be permanat too. Sounds more like loose motor mounts. The top 2 head stay bracket bolts are known to come loose now and then and it's surprising how much difference those two little bolts can make. Pull the tank and check that and all of the other motor mounts to be sure.....

For a big thumper, these bikes are pretty smooth, so if it's vibrating enough to take notice, I'm betting on the head stay bolts under the tank.

Keep us posted....

PS. Shifting doesn't matter on this situation
 
hey thanks dude. i checked my bolts sometime back and the top motor mounts had indeed shook the nuts completely off the bolts! i replaced with nylon lockers so they should be ok but yeah will check em. i can feel they're still there and seem tight just from popping my hand under the tank. sounds like if my counterbalancer nut was loose or the key had sheared i'd know about it! if the vibes i've got don't get worse then think i will wait to check it in 1000 miles when i change the oil again.

thanks for your feedback fella. it's hard to know what someones definition of vibrates a lot is! as i say i come from inline 4s so my husky vibrates a lot compared to them!
 
Yeah they will seem rough compared to 4cyl. but the 610's are pretty smooth compared to some of the other singles. Uptite makes a way cool throttle tube that has a little quicker pull and takes out ALOT of what vibration there is**************************************** It's well worth the money, especially for a SM......
 
Will have at look at those but I've spent loads on my husky so far and she hasn't even broken yet!
