Temp sensor for 250 computer

[mattmax]

I bought an Acewell 3200 speedo/odo/tach computer unit for my MC250. The company is Electrosport, they make things for moose and a few other companies.

The directions arent very specific and it seems to be up to the buyer to make half of the hardware. It has a threaded metal plug with wires coming out for a coolant temperature sensor, very similar to what cars have, just smaller.

Does anyone know if there is a plug about 3/8" wide somewhere inthe coolingsystem, or if not, where would be an ideal place to install this sensor. I can either use drill and tap some sort of metal or plastic hose connector or pre-existing fitting, I'm just wondering what part of the motor would temp be most critical?

I've got a TrailTech Vapor unit on my GG. It includes a water temp sensor too. The actual sensor is threaded into a plastic pipe (or "Tee"), and the unit is then spliced into the radiator hose. Hose clamps then secure the assembly.

I'd suggest something like that, rather than drilling and tapping the radiators themselves. I'd be cautious of the thin and soft metal of the rads. And if it doesn't work or you need to remove the sensor, all you have to do I replace the hose (or even simply splice-in a piece of hose).

Oh, I forgot to add. I think the KTM rads (which are similar to our GG rads) do have a threaded opening on their top surface.So maybe you can sneak a peek at a KTM rad and copy where/how they accommodate a temperature sensor.

Regards.

Did your "T" come with the computer, or did you have to drill and tap yourself? My speedo/odo magnetic pickup came with two screws w/lockwashers and advice on how not to position the sensor. I drilled and tapped the holes, but then wound up grinding a small pencil shaped one inch chunk of aluminum out of the front caliper frame. I just hope I didn't weaken the caliper, but the sensor fits. It makes a howling noise when I apply brakes, but I haven't centered the wheel yet and I have aluminum chip in the pads.
