I think what highlifter sells for the hondaas is a cylinder head temp gauge, but i could be wrong. But you could but a tee somewhere in the oil lines near the oil cooler.
Installing a oil temp. gauge
Where does the temp. sensor screw into the engine block on a Foreman 500?When installing a temp. gauge,can you also keep the original sensor for the factory "hot" light?

Hey,I never thought of that,,,teeing one into the cooler pipe.Would a transmission temp.. gauge for a truck work? they come with a tee to fit the cooler line.
temp is temp, I would give it a shot.
Does anyone know what the factory temp. sensor thread size is?Where is it located at on the 500 Foreman?Wouldn't it be better to get the temperature reading from the factory location rather than a cooler line?
the sensor is on the lower rear of the motor and the thread size is a metric pipe thread....good luck finding any kind of adapter at all.I also would steer clear of adding anykind of T or anything to the oil cooler lines as they are only a bolt and clamp/O-ring design which really doesn't like to be modified.honestly a cylinder head temp guage would be you best and most accurate way of telling engine temp on these motors as any condition to overheat the motor oil will be seen by a high head temp reading minutes before the oil temp guage starts to climb.ask any Kart racer and they'll tell you that an EGT guage is best then next best thing is a cyl. head temp guage for the air cooled motor.oil temp is a great idea for them but it's a pain the butt to pull it off the proper way and get an accurate reading.
How does a cylinder head temp. gauge install?Any drilling?
How about cutting the oil cooler pipe and using a compression fittingand tee to install the sensor? Is the oil cooler line some kind of crazy metric size too?

I am pretty sure it attaches right to where the sparkplug goes into the head, kinda like a washer with a wire.How does a cylinder head temp. gauge install?Any drilling?
yeah.unscrew the spark plug and then put the head temp sensor in place of the plug washer and reinstall the plug.I used them for years on my karts and they are darn accurate...right up to the melting point of the piston reliable too as you can get digital head temp guages from Mychron or Digitron.they are vibration proof and water resistant but they make nice watertight covers to put on them.u can also get them with a TON of other options on the guage.speed,EGT,head temp,coolant temp,rpm,timers,backlighting,etc..they mount with a ball and socket setup similar to a RAM mount.

That cylinder head temp. gauge sounds like the easiest way to go.Where do you buy one of these?
here are some from Ebay.the lower end Digitron gauges have CHT and Tach. so you can also have a Tach. which is handy too.for the tach to work the lead is just zip tied to the plud wire at the head and it reads the pulses.these are auto turn off gauges too.

this one looks to be a great deal.i'll find a link for the leads but they are about 20$ for both brand new.

the DT46K is what you would really want to use if you were buying new.

personally i would scan ebay for a few days and pick up a good deal on a used digitron tach.you can get killer deals on these as in the karting world guys are always buying the newest most high tech gadget and the "old" stuff is usually going pretty cheap.just use Kart racing for the ebay search or racing kart....there is always a good deal goin on.

Truckman,Thanks for all the help! That's what I like about this place,lots of info. and helpful people.Thanks again!
Summit racing has the Autometer cyl. head temp. gauge and sensor that mounts at the sparkplug. $43.95 for the gauge and get this,$78.95 for the sensor! It'll be a couple weeks before I get the money together then I'll order them.I found that the 2 and 1/16 inch gauge should fit perfectly between the gas cap and the seat.There's plenty of room under that plastic piece for clearance.
the sensors are expensive because it's a type K thermocouple.that's why i would lean towards the Kat gauges they are much cheaper if you find a deal on one.
I called Autometer directly today and they said the sparkplug mount sensor will not work with the cylinder head temp. gauges.A sensor is included with the gauge.Just drill and tap a blind hole so 2 or 3 threads will engage.The sparkplug type sensor is for a gauge that they no longer make.Where would be a good spot to drill a blind hole about 3/16" deep?
I've decided on using a VDO cylinder temp. gauge.It uses the washer type sensor that's supposed to be installed on the spark plug.Wouldn't the spark plug be the hottest part of the head?What kind of temps. do these motors run at?I was thinking about mounting the sensor under a head bolt instead of the spark plug.
expect to see 250 degrees on a regular basis.my 100cc yamaha motors that turned out 18 Hp would run between 275 and 410 degrees depending on the weather.the honda motors are a low compression setup so the temps will be much lower,but would not be alarmed to see 250 on the gauge or maybe higher from time to time.
at what tmp sould you shut the motor down because reading the temp is nice but you should be able to tell when it is time to kill the motor for safety
oh ya and BUMP
