TPS, YZ250

[casey_robert]

Hi. I unfortunately removed the TPS on my 2003 yz250 and now I have to calibrate it. In the service manual it says, "set the inductive tachometer (engine tachometer) to the high tension cord. What the heck do they mean by this? When I type in engine tachometer all I get is hour meters for maintenance. and what is a "high tension cord?"

It's the spark plug wire.

It's the spark plug wire.

Got it! I need to set the idle before adjusting the tps right?

I've never made that adjustment but knowing how it works I'd say yes, set the idle first.
