It must have been shipped from a different time zone that doesn't observe daylight savings time. Turn it back 2 hours and you should be just fine.
Its actually stock on the bike. I don't know if it's picking up both coils somehow or what but I decided to try and fix it before I shell out the unbelievable amount of money for a new one. No Daylight Savings Time bypass/observe switch on this one. Did my first trackday/ school this weekend and had the thing pegged at 14,000 in the turns. It was kinda funny.
I don't see this happening with the stock tach and wiring, so I'm guessing you (or previous owner) have tried to do some creative wiring? I had that problem with an aftermerket tach on a TL once. I was using the coil wire as pick-up and it was "double-timing" the rpm's. If you follow the wiring diagram you will find the tach wire from the ecm... use that. hope it helps.. ps still need that job, now more than ever
Check the year I had a late model tach and tried to use it on a pre-94 bike. The tach read 50% of revs. They plug in but something isnt right in the circuitry. I just used as in on mine but if yours is double my guess you are using an old model tach on a newer ignition.
