After that is done, the crank is ground again only this time it is ground for a longer stroke. Can be done to a point to gain stroke without needing the lengthen the actual throw of the crank. No idea how much can be added to the stroke doing this, but thats my understanding of the process. AaronSEIA [Reply]   [No Email]
