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 The previous version was outdated and no longer supported.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

Hi all, new to cafe husky and new to owning a Husqvarna. I recently purchased an 07 450 SMR that i think was neglected a little bit but I am hoping to bring her back to functioning properly with the help of all of you.
During the test ride it seemed to lack power in comparison to my 02 CRF 450, I figured if i gave her a fist full of throttle the tire would come up but to no avail I tried clutching it and same thing. When the bike is not running and fuel is on it takes maybe 10 seconds for fuel to start dumping out of the bowl, I figured the float isn't correct? No blinkers on the rear wires there, blinkers up front are after market and non functional wires just hanging, brake light works off back brake only, headlight is on a toggle switch mounted inside the headlight housing. It has a vector trail tech speedo that says 1500 miles but very hard to believe. With all that being said I had to have it.


So far.....
Air filter replaced
Oil and filter changed
Pulled clutch cover and clutch looked/smelled smoked - new plates and springs on the way from Hall's. Hope this solves the lack in power?
Rear blinkers on the way.

If i locate and install an original speedo will the blinkers and headlight work as intended? I see all the original harnesses behind the headlight.
Did these bikes come with a key?

Any help is greatly appreciated and my apologies for the long post. Am an excited SMR owner!

I'd do a leak down test first thing and make sure the engine is still in good condition. The SMR's are very picky bikes.
 
Be sure its a leak down test. The 450 has an auto decompression cam so a compression test wouldn't be useful.

6% on the leak down test.

Something that was noticed in the clutch assembly was very large grooves on the hub from the steel clutch plates. So i just ordered the hub. The throttle was super slow to return once it was rolled on and then let go. I lubed the housing on the handle bars as well as the one down at the carb, the cables were also lubed. Throttle tube was also cleaned and lubed. Good as new....

The carb still leaks a little out of the overflow when the gas is turned on. I am thinking of replacing the main jet, what are your thoughts on that?
 
That's a great leak down number.

The main jet wouldn't cause the float to over fill. The float needle / valve is likely worn (#42 in link below. Also see if #36 is replaceable on that carb. It isn't always). I would start by replacing that. I would also order a few extra jets, both replacement for current jetting and extra sizing. The link below is my go to for any jetting. I assumed the SMR has the FCR-MX carb but double check that.

Right on! thanks for the link.... I opened up a can of worms with this clutch, its a surflex slipper clutch. Everything I ordered from Hall's is a no go. Trying to contact these guys for parts should be fun they are in Italy and the website is horrible. Would you recommend going back to stock clutch?
 
I've never ridden with a slipper clutch, nor worked on one.

But I don't think it would be that big of an issue to revert back to stock.
