Hi, new to the forum and I have a 93 vxr pro with the 61x 701. I've been riding and thinking more power and speed would be cool, one thing Im looking into would be putting the 64X 760 cylinder, heads and pistons on my stock bottom end. IS this a good gain? Seems like Yamaha made these PWC pretty interchangeable. Im new and still not totally sure if this possible. any advice would be greatly appreciated.
