Tachometer jumps to 5K, couldn't find any info on error

OK.

access the ignitor unit. Its under the rear cowling so you will need to take this off. Take off grab bars. (4 allen bolts). Take off cowling note the screws under the cowling (metal and those plastic type things) underneath on both sides of the cowling. The ignitor unit has several plugs (harness) going into it; one harness has three wires of colour: BLUE, YELLOW, BLACK/BLUE . Remove that harness. Remove the TPS harness  at the TPS sensor end (you've already done that if you have followed my instruction above). TPS Harness has the same colours. You now have two harnesses in your hand which are both ends of the TPS lead (one from TPS, one into Ignitor) Using the meter in CONTINUITY mode, check for continuity across all three wires. ie. touch BLUE on one harness end, touch BLUE on the other harness. "BEEP" ?? If three BEEPS (three colours) come back. If not then check your wiring for breaks/faults - which will be a nightmare as you will need to remove the TPS wiring from the bike so that you are holding these two harnesses on a workbench as one single end to end cable.

If you get three BEEPS, come back - wiring is good and the fault is likely to be the TPS unit which we can check simply and replace simply

As you own a fluke I'm presuming you are not a novice in electrics so am I ok to dispense with the electrical dumbing down - so as not to unduly patronise you and make this post much simpler  :b

I see one unit with two harnesses coming into it, is it this one?:



EDIT: Could it be that this TPS is not original?:
