    Alrite, the battery I had in my bike was old, it was what was in it when i bought it, and it would seem to turn the bike over plenty fast, but it wouldnt fire, then sometimes when you let off the starter button it would fire, because the electrical load is taken off the starter, the engine is still spinning, and then it can spark,

    this would still happen is i jumped it with a truck, or with a battery charger, so I went to wal fart, and bought a $30 never start battery, and it worked great that night, this morning it wouldnt fire, not with the charger hooked up or anything, after many tries, I got it to fire after i let off the starter button and rode it home.

    it will push start and fire right up, but i dont understand how it'ss doing so with a new battery AND a charger hooked up to it, theree should be plenty of juice in the system...

    the only thing i can think of is that you have a short somewhere in your wiring that causing too much load to be drawn every time you try and start the bike.

    just a thought schooter but could it be some wiring
    like when the headlight goes out when the starter runs? does it have spark while it's cranking? a relay or something
    what the heck bike you have now, you change bikes like i change my socks :)

    Try eliminating the starter from the equation by bump starting the bike. When my bike had a Chinese battery on it , it would spin fast but not fire.
    If the bike fires every time bump starting, it's the cheap battery. I'm guessing here but the starter must pull 50 to 100 amps when cranking so a litte 4 amp charger won't make much difference.

    If the problem persists don't forget bad connections to the tci and sidestand switches.

    Could be the starter itself (Needing some tlc) but go for the easy options first!!!

    Pull the Starter and Clean-out the Electrical end.

    You likely have a coating of Carbon Dust shorting-out everything and causing the Starter to be erratic or not spin.

    You can use Electronic Spray from Radio Shack which works fast.
    Or, a few cheap bottles of Isopropyl Alcohol.
    Stick a Carb Cleaning Tube through the edge of the seal to make a hole and spray if right out of the bottle.

    The Commutator is probably very dirty.
    Heep spraying until what comes out is as clean as what goes in.
    Look at the Starter Brushed while your cleaning.
