'05 KTM Carb Needles

I know, I should have taken a picture BUT you cant move the needle on the '05 carb. There is a clip and two slots above the clip but below the clip is a nylon bushing that I could not budge! So I reverted to my Harley Days and dug out my #4 washers and put two of them in to raise the needle.

I also did a canisterectomy. That was an adventure. I broke a bolt trying to get the side panel off. The one that holds the rack. Both sides were buggered up. Luckly there was enough sticking out that I could get a pair of vice grips on it. A little penetrating oil and it came out. The bolts almost look like they were bottomed. The last few threads on both bolts were really buggered.

And I've added a Powerlet to run my air compressor. Now I get to put it all together tomorrow. What fun

Anybody have the detail of the airbox mod. I cut a 2" square hole in the airbox cover and put a chunk of UNI Filter in it. When I reassembled it all it seems like there is no point to doing that. The side panel fits WAY to close to provide any air to that opening

Do I need to cut a hole in the side panel as well as the airbox cover?

The washer is a real tight fit on several of the BSTs I've run into. The needles are hard, so you can apply a good amount of pressure without fear of breaking one.

When you run that cover you don't put the side panel on?

Thanks for the pics!

weird, can't imagine they did that on purpose... the replacement needles from Sudco are listed on a thread somewhere cugino pegaso listed them i think - nobody has tried them to my knowledge. if you got 65 bucks burning a hole in your pocket the north bay area here in cali has a shop called factory pro that makes a custom Ti needle for the BST

Sommer KTM has tested with the side panel back on - air gets in there don't worry. Others like PASSMORE have the unipod filters going all the way thru the side panel - the question is getting the airbox and pipe mods balanced (w/ the carb tuning). If you do weird stuff like Passy then you will have to tinker with the extent of airbox modification, the carb tuning, and the pipe setup. If you stay in more known territory then others work will get you close.

Well, I got that nylon shim to move this morning. Amazing what you can do with clean (and rested) hands

Now the search for some mainjets (sound familair Meat?).

She's a bit flat when you really try to honk it. There should be more grunt above 5500 RPM.

Impatiently waiting for my IDS2 quiet core (and the local Hardware store to open so I can finish putting her back together).

Assuming your relating to the inner panel not the outer right? In that case discard the inner panel.
Also make sure you use something around the circumfrence of the new airbox vent. The new vent does not sit flush on the airbox and requires (improvision)
I used some hard foam to prevent the cover from tweaking when you screw it down, it also eliminates larger particles from sneaking into your airbox.

What James said. This is one I made from CF plate... the foam on the back is 1/4" closed cell. James knows way more about foam than I do, but this stuff is semi-soft and "conforms" to the airbox edge.

You lost me babe,, I was alluding to the KTM airbox mod

btw, the closed cell is not allowing any air in

The closed cell stuff is the gasket... the air goes thru the UNI pop-ins.

O.K. I studied the photo's again and see the foam layer,, I was expecting to see something around the circumfrence but looks like you just lined the whole thing..
I also assumed you were alluding to using closed cell in place of the uni filters, my bad Doc

No biggie... it's easier to glue down a big panel of foam than a narrow edge gasket. When I was makeing rectangular screened ones, I did the same thing... used the foam to hold the screen in place.

HSR42?
