I know the oil will shorten sensor life. I want to hook one up just to get jetting set and then remove the sensor. Anyone do it on 2-strokes? How long will the sensor last (enough to tune 3-4 bikes? of just doing test runs)? Where to put sensor: in expansion chamber? Pipe leading to muffler? (have spark arrestors, so sticking a long tube in the muffler won't work). If it would work, is my assumption correct in that you would: Ride at steady 1/4 throttle to determine pilot Ride at steady 1/2 throttle to determine needle Ride at WOT to determine main jet? Spoke to a guy at Daytona Sensors, he said sensor would last in the "tens of hours" which should be plenty to sort out a few bikes, but he didn't really have any real info on 2-stroke tuning.
