Well
For all the posts I have read on the Air Screw screw assembly falling out, it happend, dang one hour of ride and all I got was dusty.

So as I wait for the new parts to come in (Ordered two kits) I will be taking the carb apart to clean.

From there I am going to look at creating a rubber insert that will go up into the air screw hole, to keep it from backing out.

Unless someone has another method, I thought that wrapping a small piece of teflon would suffice.

Moral of the story, check your screw occasionally, ya dont want to ride with a screw loose :)

You shouldnt loose the screw. Although, Id say unless you spend a couple of decades in therapy, you'll always have a screw loose my friend :)

If you ordered the kits, I assumen it comes with the spring, washer and O-ring. I ended up going to a larger pilot and running the screw at 1 1/2, as opposed to running the screw at 2 or more with the smaller pilot. I was running a 42 (stock) pilot at 2 1/4 turns and found that it acted like it wanted more. I swapped the pilot and closed the screw to 1 1/2 and its crisper than it was with the 42 at 2 1/2 out and the screw doesn't fall out. Speaking of days of wasted riding, I went out on Friday afternoon ran 8 laps and loaded the circus up. Too freakin hot. Id go three and my tounge would be draggin.

I am running a 45 with it at 1 1/2, I also wrapped a very thin piece of teflon tape around it to address vibration. But I guess me Vibrator was on High :)

I haven't checked the part numbers yet, but on my '99 400 I can't take the fuel screw out unless I remove the float bowl first. Maybe there is a diffference in the float bowls.

It's a fuel screw, not an air screw.

My local dealer,
I got two of them
Part # 3TJ-14105-40-000
I figure on two becouse some dim wad like me will be walking up and down the camp sites asking 426 owners if they have a spare.

Mine is for sale 50 bucks :D

I did check the sudco site, I was unable to determine if the parts I found were correct. I did not call should have though. I figure this is one area OEM rules so I stuck with it. Both Kits 53 bucks

Hey Shawn Got any more of that 10 buck Glue :)

Ego why didn't you just order the Kouba t-handle with the screw spring and washer. I paid 40 bucks for two of them and still have one. when I got the screw it was backing itself in when I hit the gas to about 1.25 turns out and was staying there bike ran ok but I wanted a little more so I used a little blue loctite on the threads and now it is set in place at about 1.5 to 1.75 turns out. with stock jetting also. Bike is running good finally. I know i will catch he!! for the loctite but having the t-handle on their I can just take a small pair of needle nose and should be able to break it loose. Just my 2 cents Ego, Norman Kouba is great to work with though I talked to him on the phone and he sent them right out to me at work. Frank :)
