What parts did you use to convert the speedo signal from cable driven to electronic? I have read that gsxr speedo pickups can be used, but I'm not even 100% what that means. Need some help planning this thing. I am going to try and use f4i gauges since that has been done with f2s and they are also cable driven. I am mainly concerned if the thing will fit in the front sprocket area, but need to learn how it works first too.
