Hello, my name is Frøis, and I am driving a Yamaha xs 400 special, but I am considering upgrading it to something bigger.
I am here to look at projects and learn som more about bikes in general
Hello, I have a Yamaha XS 400 special (1983), and I feel like the engine is a to weak... And was wondering if there are any other engines that would fit in the frame without to much modifications? Over time it has lost some power...
