i have been reading a lot of threads on oil temp. gauges. i was wondering if anyone has come across a unit that simply screws to the oil dipstick and has a long wire that will reach the handle bar area and have the readout mounted there. i hate to add things to my bike were i have to mess with electrical stuff (hd warranty!!!!!). i know they have them for the dipstick area only, but that is not what i want. i want somthing i can read while driving. these unit will be self-contained battery operated (just like those oven thermometers).
