Question Bike won't start

Alright so my Suzuki GSF500 will not start. the lights turn on with the key and i can start it by sprinting with the bike in second gear then dropping the clutch. When i do get it started its reving up really high and doesn't back off after riding for 20 minutes or so.

What could be wrong here? I thought it was the battery so i charged it with my car and still nothing. Im thinking starter or altenator?

You sure the battery is fully charged? You should use a trickle charger. As far as the high revs, is the choke on (the little lever next to the high beams button)?

the choke isn't on and i have heard of this trickle charger before. The lights seem to work fine when i put the key in? I tried connecting the battery to my Tahoe for 30 minutes with the car being off. I was afraid it would blow the battery so i didn't put the key in the ignition or anything. i just connected the two batteries.

To start it, you want the choke on. It will rev high... that's its job. After the bike is warmed up, you can ease off the choke and all should be fine.

I would recommend getting a trickle charger/battery tender. Mine has proved itself to be valuable time and time again. Any bike shop will have one.

If the above isn't the problem, then it could be something with the charging system... which, btw, is different than a cars (no alternator).
