I synched the carbs on my '82 the other day. I started the bike and while it was warming up I removed the synch screws from the manifolds and screwed in the vacuum lines that go to my carb-tune. For cylinders 1, 2, 4, when I took the synch screws, out the engine really stumbled, barely kept running, but when I took the screw for 3 out it made very little difference.

I did a compression check and got 150 lbs on each cylinder. I put my timing light on the plug lead for #3 and got a steady blinking. It seems to idle smoothly but maybe it would even if 1 cylinder wasn't firing it would idle pretty good. It accelerates and revs out to redline strongly. All for plugs are nice light grey.

All I can think of is that the idle circuit for cylinder 3 is plugged. The idle mixture screw for #3 has the limiter tab on it and I can turn it from stop to stop and it doesn't seem to make any difference.

Any thoughts or comments would be appreciated.

so did you sync. the carbs?

I think a lot of 'Wings do that. As long as there are no other problems, why risk creating one?
Just keep an eye on the plugs and enjoy the ride.

Yes, the carbs synched up real nice.

Yeah, I guess there isn't really a problem; the bike idles pretty good especially after the synch, and it runs strong otherwise. I have never had the carbs apart and don't really want to. I have just run a can of Sea Foam through every 3 or 4 tanks of gas.

Thanks for the response
