Checked the two screws on the butterfly in the right side carb. They were just a tiny bit loose but enough to enable the butterfly to wobble - ever seen a butterfly wobble, that must be something for you, Melena

- I gave the screws a drop of locktite and fastened them and now all my troubles are gone.
The carbs are in sync, the engine idles at a leisurely 1000 rpm and the power is back, it is just great. And with no wind, sun and a temp of 60 F the driving conditions are at a optimum.
The smiling gent in the background has an '82 LS for sale for $5000. The Motoguzzi in the foreground is one of my dreambikes.
greetings from a sunny and slightly cold north, perfect for driving though
