Well to update anyone on my last problem i thought the 98 900rr came with a 4.9 gallon tank, I ran out of gas in the middle of no where with 160 miles on 3 gallons, so I guess that solves that mystery. On to the new one. I've been told that when you hear popping and crackling out of you're exhaust on decel that your bike may be running lean. I have a D and D on my bike but i'm not sure if it is jetted. After hard acceleration through a few gears, if i let off the gas for a second then give it a little bit more it really sputters hard before picking back up again. I am wondering if this is a jetting problem, or if i'm just emptying out the bowls when i accelerate hard like that. I hear the popping and crackling out of my can when i decel, but after a 1000 miles on new plugs they still look perfect with no signs of any sort of pre-detenation or carbon fouling. Any help is apprcieated.
