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 The previous version was outdated and no longer supported.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

O.k Im having second thoughts now. I have a video on my phone I took of the bike after several hard pulls. Its idling and its really kinda noisy tick tick... Goes away just above idle. Don't think its that decompression thing, but maybe it is. I have a video i took on my phone but apparently I cannot upload an apple M4V video. Its not obnoxiously loud, and certainly is no knock. Man I wish someone who knows these bikes could hear it. It has manual cam chain adjuster, so maybe that needs ran in just a bit. I know valves usually get tighter, and not more noise.. Hmmmmmmm am I making mistake? Oil was changed about 500 miles ago.. Engine is all new inside, chain is new, 2500 miles on complete overhaul with documents and photos supporting it. Maybe Im just used to my whisper quite DR..I don't know what to do with this video to upload it, i figured about anything iPhone related could be uploaded these days.

Ill try this

Thanks Kirbybikes, It does sound like just normal mechanical noises related to valvetrain etc.. I spent a nit of time listening to thos" my husky makes noise" videos and you can definitley hear a difference on a few of them where something wasnt right. I need to figure out the procedure for the manual chain adjuster as well. I slept on it last night and woke up feeling good this morning.
 
The last time I heard my bike was some weeks ago (then the tracks were closed again because of the coronavirus and I won’t use it until they open and spring raises the temperatures).
As far as I remember, the noise at idle is very similar and in general it’s usual that a 610 sounds like that.
 
It could be the cam chain but it doesn't sound bad. On my 86 510 manual adjuster you loosen the locknut and push it in until you feel resistance, then tighten the lock nut. I understand the newer ones are ratcheted.

Im pretty sure its fine, I picked it up 30 Minutes ago. i have a whole truckload of spares!
 
Yesterday I was sitting on the floor next to my idling 630, and I heard all kinds of noises. Does make you think something might be wrong. When I stood up, it didn't sound so messy. I think it's normal for these bikes and bikes like this. There's a lot going on inside. My KLR was the same way--all kinds of mechanical noises and whirring and clacking.
 
Husqvarna's are the strongest big 4 stroke singles on the market. That comes with some sounds. What i hear in the video are the valves. But part of the sound is also made by the combustion itself. Think on clatter with big diesel engines who have this very obvious. This was a lot worse on my 1985 TE 510. When it has a nice idle run, pulls like crazy, and react fast on the throttle, its ok. By the way, my 1987 Honda XR 250 was also a noisy thing. And after tuning it became worse, but he always ran. Its not a silent tourer like BMW.
 
There sure as hell was something wrong with mine when it was making noise cos it started knocking when one of the crank journal bearings let go on the second ride of last season, havent had the bike back since the rebuild cos something wasnt making it run right :mad: but i ride it like it was stolen all the time & its held up well til 17000 miles.
The cylinder, piston & rings & valves looked in very good condition.
 
That sounds identical to my bike with only 1200 miles. Valvetrain noise is completely normal. Rod knock would sound very different than the sounds in your video, a very distinct thunk and sounds nothing like the combustion sounds and valve tick in your video.

I just recently did the valves on my bike and set the gaps perfectly in the middle of the allowed range, and I still get the same tick as you. It's completely normal.

Your's being a 610 I would keep an eye out of the chain stretch if you're north of 10k miles and ignore the other sounds. It's mostly in our heads.
 
I have come to terms with the noise level and it not much of a thought at this point. I just didnt have any experience with this particular bike. Now I do have the manual cam chain adjuster so I need to figure out when I will nesd to adjust that, but as of right now the motor only has about 2700 miles on it since complete top and bottom end rebuild. I'll just pay attention to it when I get more seat time on it in spring when some rides are scheduled!
I will say that I enjoy this thing immensley, with all the sprocket combos and tires and tons of spares and extras, I have played around and found that I like the 47 tooth on the back. I am currently running a 48 because that was the sprocket on the 50/50 wheel set, the 47 on the 80/20 dirt wheel set seems more what I want so I will swap out the 48 from the 50/50 tire to the 47 and I should about be golden. just a tad over 5K at 70 and I should be able to cruise for hours..
 
I had an obvious ticking noise on my 250, turned out to be a cam bearing. It went from ticking to death rattle really quickly, so if you've done a few miles it's probably fine.
