Temperature Sensor

Hi everyone
Where I haven’t got original clocks I’ve got this digital gauge, I love it, it’s very accurate as tested in boiling water with a thermometer, I got it in the pipe going to the head with a joiner (see pic) would you say this is accurate as it is screwed in the head?
Thanks guys

That’s not telling you the temperature inside the head&barrel. It’s telling you the temp of the coolant after the thermostat opens…
Inserting it into the head through one of the coolant pipes that runs to the carb would be better…
It’s not useless information though, it’s just it wouldn’t warn you if the thermostat failed and the cylinder/top~end climbed to catastrophic temperatures…

It does depend on what you want from the reading. Most of the time, you are just after two things.
Is there a problem with my cooling system?
Is the bike up to temperature?Both of which your mechanism would tell you.
If you want some real time dynamics of what is going on with your engine at a precise moment in time, useful for when tuning, i.e. Is the bike running lean/detonating then no.
But something like a thermocouple to the spark plug is probably going to give you a better, more accurate, reading than merely measuring coolant temperature. Since the heat is transferred from the combustion walls to the metal to the coolant to the sensor.
Vapor trail sell thermocouples that sit above the sparkplug giving a very close proximity to the ignition source.
How accurate that is, however I am unsure of.

Perfect @Calum i appreciate that! Is it something like this you mean?
Part of Description:
What is a CHT Gauge?A Cylinder Head Temperature gauge is the missing gauge on any air-cooled vehicle. Most vehicles these days are water-cooled, and every water-cooled vehicle has a vague temperature gauge on the dash which shows the temperature of the engine coolant. You have a warning that the engine may be overheating when your temp gauge heads towards the red but that's all. With this CHT gauge you can accurately measure the temperature to the decimal point up to 1300c or 2308f so you know exactly what your temps are.

What temp would you say the cylinder head gets to mate? As I’m looking at some that are 120degrees C maximum reading
What would you say is a safe reading for a 2stroke engine to be reading? Coolant was around 70 on mine if I remember correctly so no idea what would be a safe temp for the head
Thank you
