Installing an Ivan's kit and broke a drill bit off

Ivan's MB Kit and the Carbs are all done except drilling out the pilot circuits.
Pn the last hole of the last carb the tip of the drill bit broke off and there is nothing sticking out to grab.
Am I screwed ? AM I going to have to buy another #1 Carb ?
I am also looking for a more detailed procedure with diagrams on the airbox mod. I see from the picture included about what he wants but more detail would be better unless it doesn't matter that it is so precise.
Help
Thanks in advance

Can't help with the drill bit problem, but here is info on the air box mod.

Ivan's air box mod

The first pic may be wrong. Read whole thread to be sure.

I don't have any tricks for getting the bit out. I'd give Ivan a shout, I am sure someone has hit him up with the same problem. He may have a viable solution.

I'm guessing that you will have to remove the brass plug on the bottom side of the carb directly below those pilot holes. You will likely have to drill the center of the brass plug and yank it out with a screw threaded into the hole. Going back, you might be able to fill the drilled hole with JB Weld.

I spoke to Ivan today and he had me blow (135 psi through a rubber tipped nozzle) in the brass port at the 8 o clock position on the air box end of the carb.
He said it will usually will shoot it out with a little help. It did not come out ! . It is not coming out and I am afraid to poke around to much in the hole so I don't bugger up the hole.
I will try Ivan again tomorrow but I think I am going to have to find a set of used carbs.
I am pissed because my carbs are nice and most that I have seen used looks crappy

You mite try a heat gun around the area of the hole that the bit is broke in then while still hot try using air to blow it out. Aluminum expands faster that steel so the heat may help to free up whats left of the drill bit.It may take more than one try but it mite just work.

I would get a sharply pointed 90 degree pick and try to wobble it around a bit then repeat the air trick. The drill doesn't go in real far and it's at a bit of an angle, so the broken amount won't be real long. If you don't have a pick set the harbor freight ones are damn good for a buck. Just be careful using them on small items as the sharp points have no qualms about poking straight into your hands.

Just a follow up, I put the bike all back together and she runs tremendous.
Everything was done as per the Ivan's MB Kit instructions on the Pat's site. Great step by step instructions. Mixture screws are at 4 3/4, New K&N Filter with the air box moded. I replaced all O rings, seals, float bowl gaskets and float valve assemblies with OEM Yamaha parts.
The only thing is that I don't have the ability to do is sinc the cards. I have had the bike out a bunch at all different conditions and I am detecting no issues especially a low rpm with the throttle just cracked.

How'd you get the broken drill out? Or did I miss the post?

Um, I did the same on mine. I put the damn thing back together and synced it up. Works fine. Have a beer and relax.
