Well, I finally got around to pulling the outer fairing and removing the useless ambient air temperature guage and installing the new oil temp. guage. For the pos. and neg. leads for the new guage I used the original wiring off the stock guage( the orange and black wires). To mount the sending unit I removed the pipe plug from the oil pan, installed a 3/8 street 90 and then used a 3/8 to 1/8 bushing so the sending unit would fit. All went well, hid the wiring, no leaks at the pan, all's well. Then came the ride last night and either my bike runs extremely cold or something is amuck. The oil temp guage in the fairing never went over 135 degrees while my dipstick guage would read over 200 degrees. What would be the first thing to check? Maybe a bad sending unit, I would think if I had something wrong with the wiring it wouldn't register at all.
