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 The previous version was outdated and no longer supported.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

250-500cc WR 300 Common Problems??

Hi all, new to this forum and new to husqvarna bikes.
I recently bought a 2011 WR 300.
Was loving riding the bike until the common issue of the gear changing issue popped up and put me out of action on dirt biking road trip with friends.

I quickly found information about the problem and was able to fix it today.

I am wondering if there are any other common problems that occur with this model of bike?
If so I would like to rectify them before I end up stranded again.

Any information is appreciated

Thanks
 
There aren't many, but hat's one of the problems and you got it fix. The other that has happened to some, is the the failure of the Ducati ignition. The only real fix right now is either replace it or install an analog ignition from an earlier bike.

How old was your bike when this happened?
 
I have older bike, but didn't the newer ones have some that the reed block could leak air and lean down?
 
Some common issues/mods: http://www.cafehusky.com/threads/2011-wr300-bomb-proof-mods.29288/

There aren't really that many "problems." There are a few things that lots of guys modify/replace:

-Carb (rejet or swap to PWK)
-Suspension (revalve)
-Protection (skidplate, rad guards, etc)
-Thermostat (remove)

The bikes are pretty simple and pretty darn reliable.

I don't think that the Ducati ignition is a common enough failure to warrant a full replacement as preventative maintenance.
 
Add to list: Spark arrestor replacement. I now have 27 hours on her and it was time to repack. Look at the design in the manual. How in the hell are you supposed to fish out all the packing IF you even get it apart? It is not like a Japanese OEM or FMF or PC where the stinger is attached to the perforated core. I have pounded and pounded and inserted screwdrivers in to break the O ring and it ain't budging. Rear end cap won't come off either so my attempt at pulling out the Krizzman sparky to get to packing also failed. :banghead:

Spotted a Leo Vince X3 here for $135 which I'll prolly get.

Try a little heat.
 
Now I have a knocking/clicking noise at about mid range at low acceleration.
I just sealed up the reeds and same noise still exists.
Is there any way I could have done something wrong when putting the left casing back when i fixed the gear change issue?
I thought maybe something to do with the power valve mechanism inside the casing.
 
Have done. Need to use more. The aluminum casing takes a good while to get hot. Even when open though how do you dig out packing when perf core separates from stinger? Seems you'd hafta remove Krizzman S/A and then push it all out from rear?

check the spark strength/consistency if it becomes hard to start/kicks back/top end seizes for no reason
