I have a problem with my honda fireblade 900cc bike. The battery doesn't charge properly, i think it could be a problem with the regulator/rectifier. I have done some basic fault finding but have still not got to the bottom of it. Any ideas? The battery is brand new.

you are probably right with thinking its the rectifier/regulator as thats the most common fault with your problem.

Forget finding anything useful for free on the Internet. You are looking to get for free what professional mechanics pay for when they go to school. Try this. Get an older bike but not too old. Get a Clymer or Haynes service manual to go with the bike. VERY IMPORTANT!!!! TAKE THE TIME TO READ AND UNDERSTAND THE MANUAL. Then start by doing some of your own work. Start small. Don't try something like completely disassembling the engine right away. That's how basket case bikes are created. Before starting a task, re-read and understand the section of the service manual that explains the task. As you learn the more simple taks you can move on to more complex tasks. With a service manual for your bike and some hands on experience most people who are somewhat mechanically inclined will figure it out.

Check that the alternator is working.
Unplug the stator wires (left crankcase cover).
Multi-meter to 100ac volts.
With the engine running.
Touch any 2 yellow wires and rev the engine.
It should put out 50+ ac volts, at every 2 yellow wire combination.
If the alternator works, do the next test with a fully charged battery.
Mulit-meter on dc volts.
Attach the leads to the battery and start the bike.
When reving the engine, the battery's voltage should climb to 13 - 14.5 volts.
If not, faulty reg/rec, or bad connection to the battery (+) (-) or frame ground.

Many motorcycle batteries are not ready to go at the dealer and require an initial charge. Some dealers do it and some don't, I'd ask the sales folks where you bought it from and then you'll know if you've got to charge it yourself or not.
However, if they do charge it, then you may be right with your diagnosis or you may just need to check brushes/clean it.
