I did this mod with a RS 270. It read out at 265 ohm. My light comes on about the same time as it did before 1 to 1.3 gallons in tank. But the gauge is so much better now. I like that i have a gallon left when the light comes on, just means i need gas!!.
But i am not getting the mileage a lot of you are. I only get around 40 mpg. The bike is new to me with 2270 miles on 2008. And i ride it like I stole it, LOL
So maybe it is me. Maybe it doesnt like these 27 degree morning.
Love this place...learning so much about my bike
Thanks to all here
