I have a 1999 hayabusa that drains my battery in two days, no voltage.
What could be the cause?
Thanks hayabusa riders

yes, they make two difference battery and I brought the highest voltage one.
Have you checked the rectifier? What kind of mods have you done that would draw current? And welcome to the oRg!
Let me see if I can get this to where you can read it.

OK, so I FAILED! 
I would recharge the battery. Watt kind of brand is that battery? Some chinese adding their industrial waste is a waste of time you buying their chit. I'm just saying buy nothing chinese... like toof pace, doggie food chain is an empty leash you open that can and feed old people that didn't think to spend twice for a battery was wasted their money on a chitty battery days go out to eat is use kitty litter for a napkin.
OK, me bad. It was one of those is top of the line, Youwattsay if the battery takes a charge(?), you go out there at night with the lights off in the garage. You had the neg battery post off to charge the battery. Now you tap the neg cable lead to the battery post.
Did you see a big blue spark go and etch the battery cable eyelet? Sort of started to melt it? It's not the battery! You have a direct short that is a parasitic draw > Draining the battery.
Third possibility is the charging system is not working. There you need a cheap [dare I say where it is made?] volt meter to see if 12.6v is at least at the battery. Start the bike up, touch the battery with the volt meter set to volts, showing 14.4v or lower; being the battery is drawing more out of the for itself than the bike. If say 13v are pushing the scale, it's looking good.
So, we are talking a premium battery with a full charge; like brand new enough to check the charging, banging out at least 14v plus a touch give or take. Then it is not the charging system, it is the battery or current draw is my guess?

That's amazing. Anything beyond 3 years is a plus on lead acid. Lithium maybe, but I don't think they make automotive batteries from Lithium. Anyway; make sure you're not placing the key in the park position if the '99 came with that. That may have been a later model add. It burns the tail light.
Obviously have the battery checked, the charging system checked, and check for drains on the electrical system. If you have added electrical items to the bike, you could start unplugging them to see if you can find the culprit. There's a nice section in the online manuals for doing this ....
