Greetings from Denmark, i am currently working on a liquid cooled 70cc st6 RT project, and i will therefore need to watch the temprature as to not destroy the fancy cylinderkit. I have bought a "koso super slim style" 2.nd hand along with other parts that i needed for the build, and need a temp sensor for the damn thing. I am not sure which kind it uses tho, and it will have to be hardwired since the conector on the gauge is chopped off. Any advice would be appriciated   |

Hi jonas, not completely sure what you are asking...I run that same Koso on my 4T Yamaha in Thailand. I had to use an adapter "tee" to be able to screw it in.
You will want to measure the water temperature at it hottest point, which should be after the outlet near the top of the head, before it is cooled. I would say, as close the the outlet as possible.
For reference, the air cooled 2T engines measure cylinder head temperatures directly. I am sure some here will know what water temp will correlate to the head temp. Sorry, but I would be guessing a bit.
If you are asking about the wired connection...just 12v from the positive side of the ignition. (and a ground) The sensor will provide resistance to the gage for it to value and display.

The koso super slim comes with the three pin JST (wide plug) connector. Usually black.
Koso do two types of connector, so it would make sense to buy the same as it comes with.
Does your cylinder head have a screw fitting for a temperature sensor? If not you would need to get one of the water pipe adaptors. Then screw the sensor into that.
