First thing I would do is check the wiring harness from the instrument cluster (Suzuki calls this the 'combination meter') where it plugs into the system, I think there are 3 connections leading down into the main harness (but I'm not sure of the # of connections exactly). Check all the harness connectorsdown to the computer under the seat. You will probably have to remove the leftside lower fairing to get at some of these.
Make sure the key is off whenever you unplug a connector at the computer.
If these are clean and good, then check the fuses.
If still nothing, you might have to either take in to a dealer and have them run a diagnostic check on it, or buy a good service manual and try it yourself. Those inst. clusters do fail sometimes.....
Does the bike have a Power Commander on it?
If the bike has a stock exhaust header on it, and you ever decide to upgrade, let me know. I would be very interested in buying your stocker.
