2006 ZS250GS

[m0t0]

Hello Everyone!! I'm fairly new to the forums and am hoping i can get some wisdom. I picked up a 2006 zs250gs a few months back. It has just over 2000 miles on it. I cannot get it to start for the life of me. (common problem right!) I can tell you that i have spark, it seems week to me but it is there. It will shock me if its not grounded, but its not like some lawn mowers that will make your teeth chatter. I'm guessing the bike had been sitting before i got it. I tore down and cleaned the carb. I also drained and dried the tank. I seem to have good compression. I cover the spark plug hole with my thumb and my thumb will be blown off when i crank it over, but i can also press hard and my thumb will not come off. I also dont seem to have any air moving out the exhaust when i crank it over. I have tried charged the battery that was on it, and have tried a known good battery from another bike with no change. One other strange thing the battery light is always on. Normal or not? Any thoughts? Thanks in advance.
