The Carbs on my 81 1100 have just never worked right.
I have had them apart at least 7 times over the past 4 years. When I got them, they had sat with gas in them for 9 years and some of the inner surfaces were badly corroded. I have replaced every possible o-ring, gasket, valve and seal and cleaned every surface, passage and jet. The worst were the press fit idle jets but after pulling, cleaning and reinstalling at least it idled good. I have synced them at least three times.
The issue is that sometimes, not all the time, under heavy load (two upwith luggage) accelerating, I get a miss and knocking. Most recently we took a long ride (3000 miles)up through most of the southern states and on the way back the mileage dropped to around 25 mpg from about 42 mpg.
yesterday I noticed on Craigs list a listing for 1100 parts and called aboutand got a full set 82 1100 carbs for $30. They are dirty but actually look in pretty good shape. So cleaning and rebuilding I will be going and swap out the entire rack when I am done.
Hopefully this will cure the problem.
