Sounds like air being drawn in somewhere. Are you using a plain pipe to syphon, or an 'auto syphon' thingy?
I had the same problem with an auto syphon for a few brews, I tracked it down to the rubber seal between the inner and outer tubes - air was being drawn in through the seal. I proved this by dropping some clean water down between the two tubes, this stopped the bubbles appearing.
Unfortunately, it did oxidise some of the beer, but not all - with a bit of luck, yours will be okay.
