fuel gauge accuracy
OK, my XC is fairly new, just under 800 miles now. Noticed over the last couple of fill ups that the gas gauge is a bit weird. When I fill up the bike, the gage will register full for over 100 miles. The it drops pretty rapidly to 1/2 over maybe 20-30 miles, drops to 1/4 in the next 20, and then suddenly drops to empty and the low fuel light comes on around 180 miles.
Is this common, or do I have a problem? Bike is all stock, bought it new. I filled up for the 4th time today, so I'm still getting used to the bike.
