I just bought a 2006 R1 knowing that it had a bad stator which is fine it was an easy fix and cheap and the engine ran just fine. I took it to a dealership to have them switch it out because the battery would die too quick for me to get back to my house I'd have to keep charging the battery so I have the Honda dealership switch it out and as they pulled the old one out as the Stators have a tendency to break into a bunch of pieces, the technician dropped one of the little plastic pieces that go behind the rotor, (the thing that actually spins around the stator) down into the engine where I guess the transmission and gears and everything is that piece is about the size and shape of a guitar pick that's about 3/8 of an inch thick. But they're telling me now that I have to pay to have some other shop tear apart the whole engine to get that piece out. I'm planning on taking them to small claims court or filing a lawsuit against them because if they dropped it in there they should get it out by my logic I guess. but if that doesn't all work out for me I was wondering if anybody has any knowledge on how invasive or difficult it would be to do myself or how much something like that would cost.

It sounds like the stator was the stock one. That generation Yamaha stator had the magnets glued to the inside That's a big job, they'll have to take a part the bottom part of your engine. Labor alone will probably be $1200.00 if it damaged your crankshaft... another 1000.00 for a crankshaft.
Hey! Faced with same issue 3 times. Hope you will not get same experience bro. I bought chinese rotor last summer and forgot that problem forever (hope so hahaha). Here's an example -

As you can see the magnets are hidden cause of internal cartridge.
You mentioned "stator" but it cannot damage your engine as stock rotor, so you had better think again.✌

It's plastic, the oil strainer should catch it. I wouldn't worry too much.
If I were worried about it I'd get another oil pan gasket and take a dive in there.

As was said above, order new oil strainer cover gasket(actually get a few of them as they need to be replaced every time you drop the pan) and drop the exhaust which should be 8 bolts if taken off from the header and then i believe around 12 or so bolts on the bottom of the oil pan. I have had this happen to me about a month after purchasing the bike, one fell in and then had to go fishing in the oil pan but it was sitting in there and NOT A $1200 JOB! Don't pay anyone to do something that you can do and let's be honest, with the help of the free service manual located on this forum and the ability to follow directions i believe you will be just fine. Literally took me 2 tools total.(I think a 12mm deep socket and the allen that removes pretty much everything on the bike.
There are tons of topics on it. Yamaha did redesign the stator rotor so the magnets are contained. There are aftermarket ones available too. Videos on YouTube as well that show swapping stator, rotor and regulator.
Mine blew up a few years back (image attached) and the aftermarket one happened to be out of stock so I went with the updated Yamaha one.

And if you change your stator go ahead and change your rectifier.
Don’t buy EBay or knockoffs. I recommend Rick's Motorsport Electrics.
Plenty of how to videos. Changed mine on the 02 and 04 and it’s a BITCH but patience is the key!

Oh, I dropped that piece into my oil pan twice doing my stator replacement. Its easy to do because everything is covered in oil... especially if you're using the kickstand and not a rear stand. Your shitty mechanic should have just dropped the oil pan and fished it out. They probably didn't want to because that is an extra 1-2 hours of work to disassemble the exhaust, drop the pan, and then put it back together.
Small claims court isn't worth it. You'll eat up days preparing and going to court to fix what you could do yourself in 2-4 hours.
The process is
1. drain oil out of bike
2. disassembly exhaust and remove headers
3. remove 12(?) screws holding oil pan and drop oil pan
4. find/remove hard rubber piece
5. If you are going to put the rubber piece back where it goes, then do so before you replace the oil pan. That way if it gets dropped again it will just fall through the bike to the ground
6. Put new gasket on oil pan. Screw back into place
7. re-install exhaust
8. Put oil back in motorcycle
