    Hi guys,

    I read a lot about guys having good luck with the 4.0 slides in their WR250's, I'd like to give one a try. Can someone point me in the right direction in where to get one? Part #?

    Thanks!

    You would need to mention what year you have as there have been some carb changes the last few years.

    My manual said I have a 4.0 as well but it's a 3.0, you should be able to get it from any Husky dealer, Tasky's should be able to get you one.
    I did put a 4.0 slide in my bike and it runs great.

    I'm not sure what my book lists as stock, but my bike has a 3.0 in it. I did see that the book lists serveral different slides, but I didn't really want to order
    through Husky unless it's absolutely necessary.

    Thanks

    I have the same year and I'm running the JD kit with the 4.0 slide, I don't know how much more bottom end my bike could get, I've got power from idle

    You can get one from a honda dealer too. 2001 use the same carb and 4.0 slide, 2002 to 2004 used a 4.25 slide. I put one in my 07 and it was worth it, major improvement in bottom end performance.

    That's a TM carb, I couldn't find a exploded view of the TMX on our bikes, I do have an exploded view of the TMX, I needed to replace the needle/cable retainer, it got ordered through Honda and got a spare just in case. I'll see if I can get it posted on here

    There are 3 styles of tmx carbs. First gen has a slide that looks like a half round slide, the second is a flat slide that my 07 wr250 & honda cr250's use, the third is the new kidney shaped slide that 09 & newer husky's use, some times called a tmxx. The cr250 does not use a tm carb, the slides look similar but are not interchangeable.

    You can down load the parts manual for your bike @ hall's cycle & husqvarna outlet web site, maybe more. The manuals have exploited parts views & all the part numbers.

    Sudco can't get the 4.0 slides, all they can get is the standard 5.0. They told me that all the "special non-std slides" are made for manufacturers, and are their own slides, Mikuni CAN NOT sell them.

    This is what I was told.

    They did think that Honda did make a 4.0 slide from 2001-2003, but I called Honda and they couldn't verify the size of the slide from their microfich.

    I guess it will have to be thru a Husky dealer...?

    I have an OEM Husky 4.0 slide that I never used (I sold my '00 WR250 before I tried it.) PM me if interested.
