I have a 2000 400ex and when i charge the battery it will not hold a chrage. when i try to start it the thing makes a fast clicking noise. any help will be sick

 

Have the battery load tested. Its free at any auto parts store. The battery has probably failed

 

Yeah, have a test done on that one man. Also check all your electrical connections, even the frame ground. You can get a new battery for a 400ex from wallyworld or autozone for around 50 bucks, havent priced a totally sealed one like from honda or anything, but the everstarts from walmart do fine for me! If you do have to get a new one remember to take the old one with you so you dont get a core charge!
