Hi, nub here. I am having trouble with my M50's fuel injection lite coming on as soon as I ride it a few miles, 20 mi at 60 degrees, 3mi at 90 degrees F. Starts to surge and ebe after the light comes on. I took to dealer while it was doing it, he told me to leave it -- then they couldn't make it do it -- nothing wrong - maybe bad gas, he said. This has been going on for a long time. Is it safe to use a FI cleaner additive for the gas. I was so underwhelmed by the dealer I haven't been back. Any ideas??
