    Dear Husqvarna Motorcycle*Dealers,

    Replace the power valves with the provided parts, PN 8000H0239 and 8000H0240. In order to replace the valves, it is necessary to remove the cylinder.
    Remember to replace the valve cover gasket PN 800083049 before reinstalling the valve cover.

    OMG !!!

    wow.....is the stuff available yet..???


    I have mine working not too bad....jetting wise...but to be honest....my 06 CR would blow it into the weeds.....

    also I had trouble pulling 4th and 5th gears flat out on the straights.....I thought maybe this is due to the extra drive line weight...18in wheel/tire o ring chain and lighting coil.....

    Hmmm.....

    Cant answer that yet, but I sent you an email about it already.

    I am surprised as I didnt think there was any problems with the performance? I did know that the pipes were being replaced with new ones from CRD.

    There was a delay int he last shipment of WR125's (mine) as there was something about the power valves. Wonder if the recent ones already had this done?

    Great info, thanks. :thumbsup:

    Funny I had a bad weld in my expansion chamber/pipe and already welded it .

    I've also put a 52 Supersprox on the rear. Pulls like a bull if you're in the power band.:D

    I've been talking to a couple of locals the race the CR-125 (06/07) and we were talk'n about putting

    CR power valves springs into the 09 WR-125's.

    I've posted a copy of the 2009 WR125 performance update bulletin over on Dumb 2st questions Not sure if it will stay up or not...

    Did not break...just a bad weld. When I first ran it. The excess oil coming out of the chamber spewed all over the oil fill cap and engine /clutch cover.:eek:

    For a couple of seconds I didn't know what was happening.:lol::lol::lol:

    Pretty simple fix.:cheers:

    Much appreciated! :thumbsup:

    Questions
    • What happens if these things are not done? Any anecdotal info? Breakage?
    • Can I assume this is something everyone should know about and put it in the Husqvarna Important Info area?
    • Any clue how many units or what serial numbers?

    Interesting! I guess the CR has no problem pulling 13:50, sounds kinda funky to me.
    Troy the WR is a much more resilient bike when it comes to rough technical snotty conditions riding, there's no doubt a CR is quicker from point a to b though, wait til you get her in the woods.

    The bulletin just came out at 5:50 EST today.

    I get the impression that they are giving priority shipment to the bikes that are already sold.

    I dont think that the gearing is as big of deal as the PV replacement. Dealers were told that the pipes were going to be replaced a while back as some were cracking. CRD made the pipes for Husky and it is supplier issue.

    Pretty sure there is only one part number for 125 power valves. Ignition map (digital vs analog) and lighter flywheel set them apart.

    yes I agree....perhaps I am expecting too much from it...based on my CR experience

    The WR definately pulls.....but it chimes in really late and you cant let it fall off the pipe...I still need more time on it....it really handles like a dream though.....

    my CR is much more deep chested...and will accept a big handful of throttle in any gear....it never falls off the pipe

    WTF is the "Install the silent-block (PN 800069113) in the central fixing point of the frame as shown in Pct.1 below."

    Not fair to not show the diagram.......my mind is off wandering now thinking about girls on trampolines............

    Hope you all don't disapoint and it is in reality just one of theoses rubber bisquit dampner tabs for mounting the pipe!

    I cringe every time I read this. I hope my 09 WR125 I pick up Sunday does not have less power than the 04 CR125. That would suck. I'm hoping for more even if it is up top.

    No worries man!
    It's a 2 stroke. Power ups are cheap and easy.

    And you could always make it a CR-spec motor if you really wanted to.


    Largest collection in the NW :lol:
    That may be the largest collection west of the Mississippi!

    I know but i just want it to have more power than my 04 out of the box. Plus I want to keep the lighting coil for night rides / races.

    You just have CC envy :D 406 2 stroke. (guessing you WR300 still makes more power overall) :cheers:

    My '09 has plenty everywhere and is better than my '02 WR125. R Little on TT bought my '02 and rides an '04 CR125 with a FBF 135 kit. He was put off at first because how different our bike set ups where. He rides mostly South Jersey sand, which can get real deep. His bike is stock height and forks level, with lots of top end to pull throught the sand. I ride mostly slick off camber with roots and rocks. My bike is lowered, forks up in the clamps and lots of low and mid power. He took it to North Jersey for some rock riding and was amazed at how well it performed in its element compared to his 135. He was popping over 3' logs and such on the '02. He's going to put a trials tire on the rear and use it for all our enduro series rock runs.

    That said.... I think my '09 WR125 has better bottom, mid and top than my '02. I haven't dialed in the final carb adjustments, but I think it will get better yet. It is geared 13/52 and has a Power Now installed.

    Break it in fully and dial the jetting (which is more than just installing the slide and jet kit) before you pass judgement.
