Hey guys, i have been looking at buying and building a cafe racer for the road. i figured out that i wanted to make it from an xs 650 yamaha. i found one i would like to build it into but the tanks are not the same. I like the tank on the already built one but not the stock xs650s. ill post some pictures in a second. Thanks
