| by looking at the pic i would say they have drilled 2 holes throught the crank taking away the weight they just added. i believe this theoryto be better as some crankcase need to be modded just for a stock f/c crank. to fit added weight/materiel to the crank would make crankcase clearence issues. Lets do this easier if you could tell me the crankcase volume then i can tell you weather or not they added weight or took weight away
cheers matty
