I have a 2009 696 where only one adjuster screw works. The other is either welded or stuck. I bought the bike brand new so I am the original owner. Any ideas? Am I supposed to only sync the carbs with 1 screw?

do you mean the air bleed screws are stuck? you could try some penetrant around them, or try to heat the throttle body casting.

the sync screw is between the throttle bodies, bugger to get to.

Yes, one air bleed screw seems totally stuck. It is in brand new condition. The other was loose from the get-go and I could turn it easily using a screwdriver.

AeroKroil is a good penetrant. Find a screwdriver that fits the slot perfectly. Try to work the screw back and forth, not just counter clockwise. Keep dousing it periodically. You can try tapping on the screwdriver with a little hammer but don’t get carried away. Patience is your friend.

Do you know why it would be stuck like this? It's not like there is any rust or miles on the bike.

Don’t know. Blame it on random electrons. When you get them both loose put a little grease or anti seize on them to avoid a repeat.
