41FCR is the ultimate in performance [on the big end]. The 39FCR is a better all around carb for MX. If you are running in the woods, a modded stock carb that is bored and that has had the choke removed might be the best ticket. warning: If you have an aftermarket cdi and a de-choked carb on a 440 it can be difficult to start cold. Keep your stock cdi, start it with that then replace. It is easy to restart the engine after it has been warmed.
