I have a 2000 Kawasaki STX 1100 D.I. It ran great the last time I rode it! I let it sit for about 3 weeks and now the fuel gauge just reads empty and the low fuel light flashes. It is also doesn't get up and go some times almost like its mis-firring, but if you let off the gas and hit it again it usually corrects the problem and runs great but not always and when you let off the gas after it is running right some times it doesn't run right again, it is totally random. I looked at the plugs and they are all consistent, and are not soaked in oil, so it doesn't look like one cyl isn't firing. Does any one know what might be causing these problems? I really need this fixed tonight if anyone can help!
