I was told by a mechanic that it could be my carbs. Is that possible? I could see if it was the spark plug or the ignition coil. Please let me know of things to check. Thanks everyone.

Most likely the ignition coils

When you say "Fire" I think of Spark Plugs, not, carbs.
IF, you know all the plugs are firing then it may be fuel. So, I will ask; "Does it start and run now"? If, so, it most likely lost compression on that cylinder/piston. You need to do a compression test and see what all the cylinders show. Odds are that one will be off 15-20% from the others, maybe more.
IF, the cylinder is low here what you do. Pour about 1/2 ounce of 30 W oil into the cylinder and test the compression again. If, it show good (Close to the others) then it your rings, one maybe broke/stuck. IF, it still low as before, it one of your valves. I would suspect exhaust alve if it not blowing back through the carbs.
May try running some carbon cleaner through it and see if it clear. Carbon may be lodged on the rings or valve, not letting it work properly.
If that one plug not firing, put a new plug in it.

Yes, this is possible. If you develop an air leak in the intake, the fuel will not atomize properly. Gas must be mixed with air to burn. This problem will cause gas to "puddle" in the engine, thus giving the illusion of not firing. Of course, it would be a good idea to check the obvious electrical components. The worst news could be a ruptured head gasket on the cylinders that aren't firing. This causes a low compression situation. The third thing you need for ignition is pressure in the cylinder. A compression gauge is cheap, an can answer many questions. Buy a service manual if you plan to tackle any of these types of problems. Head gaskets require knowledge to repair. So does replacing the intake gaskets, etc. Good luck!

I think you mean all the cylinders are not firing. You need to start at square one,have you checked the compression, do you have fuel, have you checked the plugs.If you have a cylinder that is firing you can check all the plugs using that cylinder, this will eliminate a plug problem or find a bad plug How long has the bike been standing, if it's been awhile the pilot jets could be gummed up due to varnish. If the bike was in front of me I could diagnose the problem in 15 mins or so. Hope this has helped in some way.

start with the easy stuff. Are you getting spark at the plugs? borrow a spark plug tester from auto zone or shucks if you don't have one. If no spark, it's not the cylinders it's ignition. If spark is at the plugs, the problem is probably in the cylinder/head. If no spark, check for broken spark plug wire, then check ignition coil. Just follow the plug wires back to find it. have it tested if you can't. It's probably gonna need to be replaced.
