250-500cc Husqvarna WR250 Mikuni TMX Carb Idle Screw

Hi Guys,

I have a 2007 Husky WR250 and need to find a replacement idle screw for the mikuni TMX carb. In our country I cant find an original anywhere.

Can anyone give me the dimensions of said screw, i cant find it on the internet anywhere
Also would a normal household screw fitting that dimension work ?

Thanks for any advice

Regards.

Do yourself a favor and buy a PWK carb from Motosportz.

Wow first I ever heard of that, nice find!

That sounded so good, I ordered one right away.

I went ahead and ordered on too, as the stock set-up is about the dumbest thing I've seen in a while. I read where some variants need some carb modding. Any of you know if the CR carb is one of those? Not a big deal either way, just planning ahead...

I have one on my '06 125 and did not have to make any modifications. Best mod for the $ I ever made. A similar thumb screw for the air screw would be great too.

I was just thinking about this while riding my CR165 this past weekend. My son sent his TM carb off to Ron at RB and he put these type screws on the idle and air and it sure makes it a lot easier. Thanks for the info dirtdame; much appreciated!

I also ordered one, hope it fits OK...

had an old tm carb lying around which has a thumb screw and spring set up just had to take off some of the thread on the shaft the original was about as useful as tits on a bull.

Thanks Matt that is the set up I need on my 08 CR.

Just installed my new idle screw. Fits perfect, I can adjust my idle with no tools! What was Mikuni thinking?

Installed mine this weekend . I did have to break out the file to remove a little of the fuel inlet. I didn't get into the inlet bulge just the tip of the inlet. No big deal. Works great.
