I just purchased and took delivery of these Ebay carbs.
They are 32mm diameter. They appear brand new, so I assume they are NOS.
The float bowl O rings are a bit flattened from age.
The code on the carb bodies is VD56E which means they are 1985 Canadian I think.
They have the single side fuel entry.
They have two vent tubes connected to the T tubes connecting the carb bodies
The main jets (only checked one so far) are #90
So they look like 84 carbs after they have been modified according to the service bulletin from 1985
I am very pleased with them and I now expect my 86 to go much faster......
I have no affiliation to the seller whatsoever. His Ebay ad is a bit light on details so I figured I could fill in the gaps.
