Fault code 3K on Tacho 99 R1

Hi I have a fault code on my tacho, it jumps to 3k engine running or not then returns to normal. I was told that it is to do with the actuator on the carbs. i have checked the loom and it looks good. Would my assumption that the actuator is fubar be correct??

There's a procedure in the service manual on how to adjust the TPS. Either needs to be adjusted or replaced. You'll need a security Torx bit to adjust it.
