I started my bike today and check light came on. Where time/mileage is displayed it said either F1 or FI. It is hard to tell the difference. So, I shut the bike off and started it again. The check light stayed off and F1/FI (whichever it is) did not display. It did this about a week and a half ago to, the exact same thing. I rode it all week and it did not display the check light again but, when it did it again today I figured I should find out what it is before I keep riding. I have an M4 slipon and pcIII. How can I straighten this out? Thanks for help.
