Here is my post on the matter:
Well, its on.
Postie delivered me a set of Yamaha 40mm carburetors from a model year 2000 R1.
I will be working with a local fabricator to build a manifold. It will either be fab'd from a cut down 2bbl aluminum piece, or possibly built from scratch with a template made from the bmw manifold for the mounting flange.
I would prefer aluminum, but I may end up with steel if the cost is too high.
I am working on the plan of attack for the carbs themselves. I need to rejet them and make the necessary adjustments beyond that. Interestingly, I read that the main jets are swappable with Weber DGAV mains..yet to be confirmed. Otherwise, drilling the main jets is the way to go.
Lots to learn. Lots to learn...

This pic is from the Bogg Brothers site in the UK. I am meeting with a guy tomorrow to see what we can do for something similar.. More later..

The Mikuni carbs run a 1.2 main jet. Bogg Brothers state that a 2 liter requires that you drill the jets out to 1.8 or use Weber parts..
I ordered weber DGAV main jets in 180 and 185 to go with a 292 cam in a ported E12 head. Thinking about an O2 sensor for setup vs. dyno time. Dyno maybe for final tuning if necessary..
More later...
