the chrome casing that holds the speedo in place is easily removed (3 allen head bolts) 2 on the sides and one at the bottom (closest to you), I keep a towel handy so that when I've got the bolts removed I simply turn the chrome piece upside down, twisting to the left and setting it in the pocket it came out of (towel draped accross the tank to prevent scratches. there are 2 wiring plugs that run from the bike to the speedo case, the first thing I'd check is to see if one of them are loose (you can turn on the bike and the speedo will work, then move the plug around and see if you can duplicate the problem), the wires sneak down the front of the tank and run down the spine of the bike... if your connections are good, you can prevent moisture from getting in the plug by using dielectrical grease in the plugs... also check to see if the drain in the middle of the tank pocket is draining... hate to see a spider making a nest in it, dying and clogging that drain. you can change the speedo by taking another three screws out.. I can't imagine how expensive a speedo would be from a dealer, but if you have any local junk yards you may get lucky and find one, also watch on ebay... you might get lucky. ~Dave
