Sonic carb cleaning?

[darrsi]

Just a quick update, as the garage I took it to in the first place isn't open again until Monday the 13th I took it to the garage i used to get the Dyno done on it a few months back.
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.

I had my bike jetted, after a full carb clean at PDQ Dyno centre.
But it just didn't feel right at all, so I let him know and he put it all back to standard for me and it then ran fine again.
