As some here know, I have issue with engine shut down while riding. Only code that comes up, if it really is a code, is (no r 5P) Is this a code and if so what is it?? The code read out display in the odometer, reads as follows, ( P55PTb ) When you go thru- each set, it has appeared with the first letter "P" in the code set and the last letter "b" in the code set. I can't find any explanition as to what the represents. Any idea what the code ( no r 5P) means???
