Would first like to say hello to everyone as this is my first post. I ride a 96 King and just put new Dunlop 402's front and back. There is no speedo gear on front wheel. After installing tires and taking bike for test ride the speedo seems to be way off. I guesstimate that I was traveling 55-60 but the speedo was only showing 40. Any thoughts on this and is there any adjustment. Thanks in advance and looking forward to many future posts.
