Hummmmm............... Your right but they are wrong. I know as I bought the carb from a 2011 150XC and it IS a 36mm PWK A/S. They are propriatary as they are only available from KTM.
PS: I was just shinning you on. LOL

I know Dwight.....

P.S. I'll call Mark Hyde.....

Dwight,

You can actually get the 38 for the 2011 150xc, it is just an option and probably is the same as the 38 that comes on the sx. At least that is what it looks like on the parts fiches I was looking at. Of course what do I know as I am a Husky nut.

Tell "Possum" I said hello. I saw him this weekend. Betsy was with him. He was helping Alan prerun the enduro and running the KTM Demo rides.

I bet eventually that KTM will go to the 36mm on all it's bikes. I think their big bikes run 36mm also.

My guess is you are completely right Dwight.

So how do these ports look? Should the "divider" section be so flat on top or would it flow better if filed to an edge? I laid a new gasket on it and it will require just a small trim.

Typically if you knife edge the divider it improves the flow.

NW Rider, I just spent an hour typing out what you need to do and lost the whole darn thing. I'll send you a PM and call me and I'll walk you thru it.

new thread! i wanna read this stuff too

Welp. Got my Stealth Racing idle screw today. I excitedly removed the carb, withdrew the old screw, inserted the new Stealth Racing screw... and...

... it went in two or three threads and got tight! DAMMIT !!!
I've emailed Stealth about the issue. I'll keep you posted on the outcome. But for now, I'd advise avoiding this product while I do the research for us.

BTW, my ZipTy air screw arrives Friday. Stay tuned.

krieg, that's a bummer. i ordered one right after MattR posted too

thanks for the heads up.

Let us know how yours turns out. I may have gotten a defective one. Just be VERY careful and don't try to force it. If it's like mine, the first turn or two makes it feel like it'll fit fine.

will do, should be here this week i assume.

Interesting..... I have a Stealth idle screw on my TMXX and had no problem. I did take a little off the fuel outlet spigot, as per instructions and ground down the knob for better clearence. I also had one on my '02 WR125's TMX.

I did the same Norman. No go.

FWIW, if you grind the outlet spigot properly, you don't have to grind the knob.

Has to be a mislabled screw for differrent carb.

I also have the stealth screw on my TMXX and after grinding the spigot it works great. I also think you must have gotten something mis-labeled Krieg. Call them and see what they will do.
