Keihin FCR 41 jetting

Post by micap »

I have managed to sort a set of 4 Keihin FCR 41's, previously fitted to a Honda. The plan is to use two of them on my 750 sport, in a split setup with Malossi manifolds.

Does anyone have any advice on the jetting of these? I have searched around, but it seems that the popular solution for the 750 is the 39 mm, but I remember reading somewhere, that there is no reason to not go big with the FCR's. I am currently running Phm 40's, so I guess anything will be an upgrade.
