I purposely let my bike run out of fuel on the regular fuel petcock setting. I wanted to see how much fuel it would take. I filled up and noticed it only took 4.3 gallons arent these supposed to be 5.3 gallons with a 1.06 reserve or am I misreading it and the total capacity is 5.3 which includes the 1 gal res? (Though 6 gallons seems like alot for 1990.)
