Picked up a 2013 450 that I converted to a dual sport/supermoto. Everything was working fine untill I put on the supermoto wheelsand rode it for 20 or so miles but used the stock speed sensor as a spacer. I sent the sumo wheels into warp 9 to replace the hub with one that has the wr speedo drive. now when I put my dirt wheels back on the speedo reads 0 MPH. I have taken it out and greased it and still can't get it to read anything. Is the something that I can do to fix or or did I mess it up running it with sumo wheels?
