They certainly wouldn't be able to clean just the inside and leave the outside dirty. Sounds to me like they've just run some carb cleaner through them and they're just bullshitting you!

As everyone else said, take it back and demand that they sort it out, you've paid for a service which they haven't delivered

I had a good look at the carbs at lunch and they are pretty dirty on the outside, i cant see how he could of removed them and not given them a clean to at least make it look like he had worked on them?
The bike is certainly running worse, so i am not entirely sure what he did, and because he is not back until the 13th i have just got to wait, but as with most people on here, you get to know your bike and all its noises and issues and its definitely not right.
What he will do about it remains to be seen and whether he will resolve the problem is another? but there are a few other garages by me, one being a Yamaha main dealer (which i would imagine is going to be expensive) and a few other small places.
The Yamaha one mentioned clearances and  stuff but to the cost of over £350 to sort it, although he did say a pressure test would help to see what the problem is should it be that??
The dyno i had last year showed the bike to run lean at 5 - 7k revs and they suggested a dyno kit/rejetting which i know a few people on here said is a waste of money and as the bike if getting on a bit now i dont want to be investing a ton of cash into her when it might be easier to just get another one, but you never know if the one your getting has more inherent problems than the one you already got.

He had a good look at the bike and confirmed my suspicions, that the carbs hadn't been in a ultra sonic bath and was hard pressed to even tell if they had been removed at all??
I spoke to him about the issues and they guy still had my dyno graph on file and remembered how the bike ran.
We spoke about how it was still running lean between  5 - 7 k and that if i chose to book it in there i could have the carbs fully stripped and properly ultra sonic cleaned and then they would dyno it again and set the carbs up from there, even if it meant going back on the dyno 10 times (but its a set price for the work so whether it goes on once or 10 times its still the same cost) and as a last resort if they cant get the bike set up with the standard parts they would have to fit the kit, but at the moment, there is still no knowing if the carbs haven't been tampered with in the past and had parts replaced or a kit fitted??
Although I am still unsure of this as i know i mentioned this before and a few people seem to have had mixed experiences with dyno jet kits? where some have worked and other made the bike run worse?
I am also considering getting a second hand set of carbs to see if maybe this cures the problem rather than just spending loads of money on the bike and getting no where.

If you've done any sort of basic maintenance you will be able to do it. It's not rocket science. There's no adjustment points that you can get wrong other than the idle mixture screws so you if you leave them as they are you can't do any harm having a go yourself. The worst case scenario is you damage a screw or jet and you have to get a second hand set of carbs which you're thinking about doing anyway. I can't see how valve clearances would cause a flat spot at a certain revs so I wouldn't worry about that. Have you got the basics right like air filter, spark plugs, leads and caps, throttle position sensor all good?
