hello everybody, i have just joined up and was wondering if anyone can answer my problem?!! I have a 1999 cbr900rr and it has been extremely reliable untill recently. I bought a new battery a month ago and when i go for a big ride or leavethe bike.sitting for a few days the battery drains itself flat. im guessing its an electrical problem with the bike, any ideas?

 

The electrical system is simple on our bikes. Most likely it is your rectifier. Also, look around the forums a little. There is a section for the 900RR. People there can help you better. Welcome to the forums.
