I have a yamaha r6 and every morning when I go to ride it, it will not start. I charge the battery for about 20 minutes and the bike is ready to go. When I plug the battery into the charger it shows that the battery is at about 5o percent , after the 20 minutes the reader says 100 I take it out to ride and then in the morning it does not want to start. The battery is only 6 months old. Bot during those 6 months that I had the bike it was in he shop getting frame work because it fell. What could be the problem?

take the battery out and take it down to checkers or auto zone or whatever auto parts store you have near by and have them test the battery. If it's fine, put it back in the bike and get a multimeter and test the voltage across the battery terminals with the bike running at 5,000rpm. Should be around 14.2v @ 5krpm... if it's much less it's a bad stator, if it's much more it's a bad regulator/rectifier, if it's right around 14.2v give or take half a volt, you have a short in your wire harness somewhere.
If the battery is bad and you have to get a new one, make sure it's the sealed maintenance free type, don't get one you have to add battery acid in to.

Well, if it's "clicking", then it means it IS electrical, because the engine starter isn't getting the amperage it needs to start. You need to take the battery cables off , clean them thoroughly of any white powder residue ( battery acid solidified ), and scuff them down to a silver sheen so they'll make good electrical contact. Check your cable connections all the way thru, to the starter, etc. Look for loose bolts/nuts, corrosion, etc. You may think you're charging the battery, but if there is white powder all over the connections, you may not be charging it effectively. You'd need a voltmeter to check not just the cable you attach the charger to, but the actual terminal in the center, to see if the voltage is getting TO the battery. Basically, just clean both battery terminal ends, cable and battery, and retighten, then recharge. Are you using a small trickle-charger, or a larger, more professional one? If a trickle, it'll take a long while to charge it up enough, maybe 6-8 hours. If you're leaving it connected, and you have a short circuit, you won't be effectively charging it, either. I've jump-started my motorcycles with automobiles ( if you have a 12-volt system, NOT a 6-volt! Don't try it if you have a 6-volt, it'll damage it ). Anyway, make sure all your connections are clean and shiny, and you have an adequate charger, or alot of patience.

Does problem only arise when bike is left idle for a long period of time? Then it would appear you have a drain on battery. Something is draining current while bike is parked. To check this, with bike switched off and no lights or alarm on, remove one battery connection. If there is a spark between cable and terminal when they are close to one another, then something is taking current.Could be due to a number of things including a short anywhere in wiring loom. Can be difficult to trace.
You can confirm this diagnosis by disconnecting one battery lead before parking for the night. Reconnect in morning and try to start it. If it starts, then there is a drain, if not, then suspect battery or charging circuit

Purchase a "hydrometer" from an auto parts store (it looks like an eye dropper and costs less than $10).
Remove the battery from the bike and give it a good charge.
With the hydrometer - check the state of charge of each cell of the battery (no can do with a sealed battery - if it's maintenance free, pop the sealing strip off).
Let it sit over night.
Test it's state of charge the next day.
If it went down, the battery isn't strong enough to hold a charge.
From sitting so long without a trickle charge at the shop, it could have weakened to the point where it won't hold a charge.
Might need to be replaced.

First I'd suspect the battery.
If "it fell" hard enough to need frame work, and then spent six months in the shop without being charged it could well be dead.
Before you change it though, check the charging system, (It's a simple voltmeter test, running vs. not-running). If the battery's not being charged,
it would run down as you ride.

The battery is not holding a charge. It may be a bad battery or something draining the battery over night.

check the outputs on your generator/alternator to make sure they're charging the battery properly. If they aren't - replace it and the battery. If they are - replace the battery and start charging the new one with a trickle charger when you go long periods of time without riding it.

Sounds to me like the battery isn't holding a proper charge.

It sounds like a faulty battery to me. I have problems with mine and it's about the same age as yours. But I ride with the headlamp on and don't really give it enough time to charge.

Buy a new battery every 3 years, no matter what.
