How hot do you think our engines get?

I'm looking at using a hall sensor for an ignition project.

The sensor says it can be used from -40C to 125C ( 257F)

If anyone has one of those thermal heat guns that give you a temp reading. Would you unscrew the left-side cover and shine it on the ignition pick-up sensor and tell me how hot it is.

I tried finding numbers but I wasn't able to.

 

Haynes manual doesn't have that info, just checked. A few of the guys here have the full shop manuals and may be able to see if there are any kind of spec there. Which bike do you have?

 

i have a temp sensor on the valve cover right on the cam tunnel part. it holds the max reading and right now it says 275f, after a few years of riding. so that's right over the heads, setting in traffic on hot summer days. i think down on the ignition you'll be ok

 

I think you're right. I let the bike run for about 10 minutes to run. Then I pulled off the ignition side.

It was warm, but I was able to touch the pick-up sensor and pieces without burning my hand.

Thanks for the general reading though. 275F at the heads isn't bad when the sensor can handle 257F and is at a lower and cooler part of the engine.

 

Be careful. Our bike's engines cool and re-charge as we ride. Ten minutes is a bit of time for it not under load. Keep a fan(s) blowing on the engine and try not to drain the battery. Hope this help.

if you think you might run the battery down, just unplug the headlight.
