Hi, i have an A+ crank with the rolled fillet radius's and am considering machining the mains to take a set of lightened S rods i have . The crank needs a grind anyway ,but is this to much on an A+ crank ?? Any thoughts appreciated.

Yes it can be done , but you will also have to widen the the BE width on the crank or thin the rods down .

Need a good 0.090" fillet radius on the big end journal and getting it heat treated would be a good idea .
