I just got a 2004 1150 RT . A former Cal. HP bike. I have converted it with aftermarket seat and passenger pegs. I love the bike. The speedo lite is out. I bought the bulb. Do I have to disaassemble the cluster or is it simple please give me suggestions. All the fuses test OK. Also the grip heaters don´t work any suggestions. The Clymer manual is pretty lame. thanks
