    tach wire 08 R1

    Can anyone tell me what wire to hook tach. I don't have the data center that comes with the bike. Wiring diagrams only show the tach being connected to the data meter. I hooked in one of the coil leads but it shows way low on the rpm, I guess cause it is only reading one coil. Help please, got a race today. Thanks!

    There is a yellow/black wire that gives the tach signal to the bike gauges.Try that one if its still in your harness. Many aftermarket tach's also have an adjustment that allows them to give the correct rpm for various # of cylinders in an engine when connected directly to the coil.
