My speedo drive spins and in the right direction when not connected up the top to the speedo, and when I put a drill on it, it works fine. But when connected and riding along it doesn't move. But the odometer moves backwards. The speedo is new from mikes xs I was thinking it might spin but doesn't spin quick enough as the drive is worn and it's vibrating the numbers backwards on the odometer. Any help or input appreciated its doing my head in haha. I'd rather not buy an electric one as none match the one I have and want to work with what I have. Is there new drives available or has anyone fixed an old worn one up. Thanks
