Question about 2003 Yamaha YZF 600 R thunder cat
I have charged my battery and the bike ran great I shut the bike off and when I went to start it the next morning it just gave me a click and that was it but I pulled the battery out and put it in another bike and it fired right up so it is not the battery...also all the fuses are good
If the batteries good its probably a bad ground. make sure the hot and negative wires are good from the battery AND where they end up. The ground wire usually grounds to the frame somewhere, trace the ENTIRE wire!

Hi and welcome to FixYa,
Initially, pls try recharging the battery again. Remove the connector to the voltage regulator. Start/run the bike. If it lasts more than "3-5 minutes" then you have just confirmed a defective regulator. The voltage regulator would look something like below image.
This page may give you additional insight.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Try putting in new, stock spark plugs. Check and possibly replace the air filter. Charge the battery. Get the bike running then check the battery voltage at 2000 rpm. It should show 14volts or more. If not, get the charging system checked. Get a can of starting spray (for future problems).
Get the compression checked. Your bike is 21 years old and I will bet that the valves are needing to be reseated. Check the valve clearances with a cold engine and reset valve clearances as needed. Check the area where the head contacts th cylinder. Any mist of an oil stain? Tighten the head or replace the head gasket. If replacing the gasket, now is the time to have the shop lap re-seat the valves. Have them sync and balance the carbs as well. Your bike will now have its' manners back and show you the dedication it should.
