I recently got a 1988 Polaris trail boss 2x4 two stroke running and was wondering if there is any way to test the oil injection system without removing anything. I marked a line on the oil dipstick for when I take it out this weekend and am going to likely run premix but was wondering there was any other way to tell. I ran it with straight gas and oil in the reservoir and when I revved up more smoke came out but I'm not entirely sure it wasn't just from before. I also ran it with mix and injection and manually moved the throttle linkage on the oil injector upward and took a photo of the emissions of both with and without the injection lever. Can someone help me decide.
