So I've been working on my late father's 2002 m2 cyclone. I've got a basic knowledge of working on bikes but am still learning.. Its mine and my brother's now, and he got shipped off to katar and I was hoping to get his bike working for him when he got back. He had it working before he left 9 months ago but hasn't been used since.
I've tried putting the battery on a tender but it won't take a charge. He mentioned something about it grounding out before he left, but I can't get in contact with him right now for reasons, so thats all the info I got. I rode a 1982 honda 750 myself for a few years and this bike a handful of times when my dad was alive.
Sorry for the novel, but that being said, how hard to work on is this thing? its a step up from my bike so I don't want to screw up anything, it being sentimental. Also, I heard finding mechanics for it would be hard. I'm in northbay near san fran. Any suggestions on fixing the problem or who could?

Get a service manual first.
Not sure if grounding out means not
First check to see the ground strap is
clean and tight .
It could also be the clutch or side stand
These bikes are easy to work on to a certain point.
Remove the seat and tail and tank and check all the wires .
Others here are more knowledgeable

Well the battery could have grounded out or shorted if the terminals were not tight. But yes they are not difficult as said above take the seat off and the tank. Check all areas where the wires make sharp turns etc. check and clean the grounding strap at the back of the frame to the swingarm block. Check your fuses. Install a new battery and make sure you tighten the terminals completely. Test fire the bike with out the seat or tank on

I thought "grounded out" was a generic term for the stator failing by shorting out which would zero the charge for the battery eventually killing it over repeated external charges and complete drainings
You'll have to remove the battery and get it tested and get another if it is dead. After installing the new battery, see if you can start the bike and warm it up enough to put a multimeter across the battery terminals to measure the voltage across the terminals at a bit above idle.
What sort of maintenance did you do on your Honda? FWIW I find working on American bikes easier than Japanese bikes.

A lot of us have had problems with the clutch/sidestand sensors. The easy solution is just to remove the switches and attach the wires, if you trust yourself enough to put up the sidestand before you ride away and have a habit of holding in the clutch lever when you start the bike.
I'd definitely start with a new battery, and once you get one it'll be easier to figure out exactly what the bike is doing. If it's the clutch/sidestand sensors it should be easy to pick out. Unplug the sensors and connect the two ends on the harness side. If it runs like normal, it was one of the switches, and you can just leave the switches disconnected. If you can get it started, the multimeter like Hogwash mentioned is the quickest test to try. Definitely make sure all of the connections on the battery and grounds are tight as well, things have a habit of vibrating loose on these bikes.

If the battery won't take a charge, you have a bad battery. Simple.
Motorcycle batteries generally suck and don't last as long as car batteries. I get 2-3 years out of one generally before it needs to be chucked over the lemon tree with everything working right.
"Grounding out" to me means the hot side is getting to ground directly - that is very bad for a battery and would lead to the above condition (if it doesn't just cause a fire and burn the whole damn thing up).
Get a continuity tester. Turn the ignition switch OFF and go tot he fuse block and look for circuits that still have continuity from fuse side to ground.
Sometime it is something weird, like the time I had my foil covered seat pan short out my circuit breakers when I would turn left (not on a Buell, custom bike with a custom seat).
