I always wunder how they come up with the new carb settings for a prototype engine. Do they they just toss in the older carb settings, go riding and say to each other: oke that won't work, let us try something different.
Or can they estimate in the factory, on the drawing board, the carb settings and just make a few minor adjustments later on?
