Never seen that or even heard of it.A little off-topic but related. I find that the sync screws are super sensitive just touching with the screwdriver changes it. I’ve also noticed that the sync changes pretty easily. Is there a way to tighten up the screws, like adding a washer or something on the threads?
The front sync screw on the right hand side (#4) syncs #3 & #4 to the left side carbs.
sync procedure:
-2 is the master carb, everything is sync'd to it
-sync 1 to 2 using the sync screw on 1
-sync 3 to 4 using the sync screw on 3
-sync 3-4 to 1-2 using the sync screw on 4
If you're all the way out go back in. If you're all the way in go back out. It's that screw that's the problem. If nothing changes as you turn that screw then you have a problem like a missing spring or broken linkage or something.
Not the point I was making. If it was all the way out already, which is what he suggested, I just wanted him to turn it all the way in to see if any change at all took place.The right front screw needs to be backed out, not screwed in...according to your gauge
* I'd set aside bit more than 45 seconds for this. lol
I will roll the bike out to the driveway.That picture is awfully dark. I went out and took a picture of mine. I want you to check yours against mine. See that red circle? See how I have the tension spring wrapping over both edges of it?
(You may need to download the image or open it in a new browser to increase size to see it clearly.)
Make sure your screw has those spring ends lapping over it.

If those spring ends aren't there, you sure as hell can.I cannot prove he did anything wrong.
