06 ADV 1st Wrenching Nightmare

Well just got my 06 adv last week happy as can be,until I thought Id try changing the main jet.Ive read many threads on this topic thought it would be pretty easy,wrong!Ive changed jets etc on my 525mxc and my 300exc no brainer.I knew from threads it was a little pain in the ass,but what a nightmare.Can anyone refer me to a specific thread on the best way to access the bst40.I took back airboot to airbox out still couldnt get that SOB free so than loosened the sub frame to access better,had to take my pipe off etc to pivot subframe.Got to be a easier way?.Now Im having a problem returning subframe to mainframe by the top two bolts where the rubber tank pads are which one ripped to add to my misery.The problem is the two flanges on sub frame should seat to the outside of flanges on main frame,but the flange on the right is butting in line with the one on the main frame making not possible to go back to proper position.Any tricks getting that subframe flanges spreading them to return over mainframe flange?.In theory it should just pivot right back!Any help would be great.
Thanks Doug

Ive read many threads on this topic thought it would be pretty easy,wrong! Ive changed jets etc on my 525mxc and my 300exc no brainer. I knew from threads it was a little pain in the ass,but what a nightmare.

Can anyone refer me to a specific thread on the best way to access the bst40. I took back airboot to airbox out still couldnt get that SOB free so than loosened the sub frame to access better,had to take my pipe off etc to pivot subframe. Got to be a easier way?.

Now Im having a problem returning subframe to mainframe by the top two bolts where the rubber tank pads are which one ripped to add to my misery. The problem is the two flanges on sub frame should seat to the outside of flanges on main frame,but the flange on the right is butting in line with the one on the main frame making not possible to go back to proper position. Any tricks getting that subframe flanges spreading them to return over mainframe flange?. In theory it should just pivot right back!

Any help would be great.
Thanks Doug

Fixed.

First off, why did you want to remove the carb? To access the main jet you simply use a stubby or 90 degree screwdriver to open the cap on the bottom of the carb (drain the bowl first and shutoff the gas eh? ). The main jet sits just inside casually awaiting quick changes.

To access the other parts of the carb that are generally well accepted as standard mods you simply remove the tank (close the petcock and the crossover valves (x2) first eh? ) and the top of the carb is awaiting your tool. The slide and jet needle are sitting just under the diaphram. Like you wife has probably said a hundred times, don't pinch the diaphram!!!

I have read once or twice that folks trying to access a third jet, what was it the idle jet can do so by (I think) unhooking the airbox and reaching it from there... but I had better find that thread first to make sure WTF I am talkin' about. And besides, changes to the idle jet are not generally considered standard. That brings up a good point: remember to do these thing sequentially, so you know the effect of each mod (both in and of itself and in concert with the other changes you did previously).

Now WTF was the rest of your question? Ah, I have not removed my carb, but creeper has and he told me if you have to you should be able to free it by bending the boot that connects it to the engine (already disconnected from the airbox eh?). Or was it vice versa... But you don't have to move the rear subframe!!!

I have also read of folks having trouble getting the rear subframe back on... I think you will have to have someone help you put it under tension to get it to line up so you can fasten it. But that thread should also be found. Bummer, since you didn't have to do this!

So in conclusion, the standard mods are not a nightmare; they are easy. Not knowing WTF you are doing is a nightmare. I know; I have been there and probably will be there again real soon.

Thanks meat for the help.My approach was the same as my 525 loosen intake and airboot tilt carb at 45 or so for a visual of jets, but with 640adv not so due to frame being in the way.So I called mechanic at dealer and asked him and he told to pivot subframe, !st mistake listening to that advice?I just wanted to see wtf I was doing hence my motive for a visual.My bikes still in pieces due the fact that I cant get subframe to line up on flanges on main frame right where you bolt next to rubber tank pads on top next to airbox any assistance would be appreciated.It aint easy lining that sob up.Any tricks out there?

I had the same issue. I lined it up as best I could then got my assistant to give it a big force full shove forward.

There is nothing to see in regards to the jets - did you change the main yet? see how available it is w/out removing the carb (by design...)?

Anyways, here is the thread with some tips on the subframe; worked for one fella: http://www.advrider.com/forums/showthread.php?t=126636

And here is one discussion of carb tuning that shows the third jet:

Can't find creeper's blurb on removing the carb, but perhaps he will show up before I find it later.

Remove tank, disconnect everything attached to the carb, pull back airbox boot, pull carb back out of intake spigot, pull carb out thru the top between frame rails.

Thats it,

Hey Thanks for the help guys.Subframe problem solved used a C clamp to pinch in flanges on main frame then subframe slide on, lining up of bolts was a bit of battle but won the war.Meat thanks for the links very helpful.Think I am missing something on the removal of carb through fork in frame up top on 06 adv, I think without pivoting back of airbox.Black plastic box/w wire on right side & throttle cables on left seem to have to be removed to physically get carb out top between frame,a lot of work to exit carb for this old dog.

Thanks again, Doug

Bump for an oldie but a goodie. I'm just having fun and games doing this myself today. Nice to have a simple sequence of events to follow.

Previously when we refit my sub frame we used a reversed C cramp, which spreads instead of squeezes. and applied it just behind the where the sub-frame bolt holes are. It doesn't take a lot of pressure to spread the subframe 1-2mm, just enough to help it slip on.

Updated key words to help search engines to find next time:
KTM LC4 640 Adv carburetor removal instructions (American spelling)
KTM LC4 640 Adv carburettor removal instructions (Commonwealth spelling)
KTM LC4 640 Adv carburetter removal instructions (Commonwealth spelling)


Right... now it's time to get may arse back out to the shed and apply what I just learned...

Normally the last jets you would mess with. Normally only change one or the other. I didn't notice any difference on my '03. The Austrian Uber babes on the KTM production line do them jets up real tight, in my experience.

Lining Subframe back up

So, whilst riding the A2 from Myales to Nairobi, my subframe decided to pop out, pulling the carb off the engine. Obviously, being in the middle of Africa, on my own, you have to work things out yourself.

So, armed with a ratchet strap and a tire lever, it took all of two minutes, here's a pic:


OK, so not so clever now as I can't get the link in. But you tie the luggage rack to the handle bar, then ratchet it up...
