SOUNDS LIKE CARB NEEDS TO BE TAKEN APRT AND CLEANED VERY WELL AND MAKE SURE YOU ARE GETTING SPARK IF YOU ARE GETTING SPARK AND THE PLUG IS GOOD THEN I WOULD PROCEED WITH THE CARB AND IF THERE IS ANY GAS IN IT GET RID OF IT AND START WITH FRESH GAS

The problem is a bit of trash is preventing the float needle from closing fully to stop the flow of gas. Try this; drain the float bowl then close the drain and turn on the gas. Tap the float bowl solidly with the end of a screwdriver handle. The object is to free up the float / shake loose the trash. If doing that a couple of times does not fix the problem, Remove the float bowl and spray the interior of the carb using spray carb cleaner. Pay special attention to the float pin area. With the float bowl off you should be able to gently lift and lower the float. Lifting should shut off the gas and lowering should let the gas flow again. If the float shuts off the gas when raised, put the float bowl back in place and see if the carb still over fills. If so, then the float is defective and you will need a new one. Please rate my answer. Thanks. tombones49_151.gif

I looked all through the manual and could not find a fuse box. It looks like they may all be inline single fuses.

Fuse replacement needed.

You don't mention which bearing it is or how you know that they've gone bad. In any case, here's a link to the service manual.

Something has to be draining your battery. Try to find out what is still pulling power. What could still be running even when your ignition switch is off. Usually it's the parking light. Depending on your make the last turn of your key after your lock, is a parking light notch. My Hyabusa has that kind of notch and I'm always being alerted that my back light is still on after I'm in the house.

If the battery won't hold a charge take it to an auto parts store. they'll usually check it for you on a load tester for free. Typically the issues of the battery discharging stem from the charging system. I would check the stator output as well as the regulator. More than likely your problems stem from those areas.

right in the back of gear box same size as the drain bolt,. put in the right amount, per the manual, if you put in to much it will over flow,.

There's a button covered with rubber on the left side of the dashboard. Using a thin stick, push this firmly and hold (while the bike is running) for about 1 minute. Fixed.
