How old is the battery?
Look for loose or corroded connection at either end of the main battery cables. If you drain the battery enough times......or leave it down too long.....you will need to replace it TOO, regardless of what the original problem was.
Better to check battery with the bike running. At idle (~1K rpm, not loping idle) it should be a tad above the bare battery voltage.....like .1 or .2. Above 2K, it should be at least 13.0 V. and 14.0 is typical if the battery is not fully charged and healthy.
Bottom line: if it reads 13.0 or more when the bike is running, then it is likely that the battery is the problem.
One simple way to test for alternator function is to rev the engine and watch the headlights. If the alternator is working well, you'll see the lights brighten from idle.
12.2v with engine running sounds like you have a charging issue, i.e alternator.

Check the power regulator from the alternator to the battery line.

In the middle of the drain pan. The drain pain is roughly half-way between the front and the rear. You can see it better from the bike's right side if you're lying on the ground.

Forks on a motorcycle are usually comprised of springs, oil, and valves. Some have the option for air, some are nitrogen charged. Some also have adjustments for preload and rebound. Best bet is grab an owners manual to be sure which type you have and go from there. If yours are pressurized with air or nitrogen, check the pressure to see if it is within factory specifications. If not adjust accordingly. *WARNING* Many of these style are easily damaged from too much air pressure say from that of an air compressor like those used for automotive tools. If you need to add pressure, the safest bet is to use a simple hand/foot operated pump similar to those used for a bicycle. You may also call your local Suzuki dealer and ask if they have a lighter spring for the forks. Swapping these can be done DIY with patience and proper tools or imagination with other tools you may already have. One last option is to replace the oil as it maybe time for it to be serviced and just fresh oil may do the trick, that is if the bike when you got it originally felt better than now. I wish you the best of luck with your bike and safe riding from a fellow rider.

The problem is more likely to be ignition related. And yes, they do have a fuel filter. Usually in the fuel tap, but sometimes in the fuel line as well. Fuel starvation would not cause the symptoms as you describe them. A misfire would, you would get unburned fuel in the exhaust and it would then be ignited by the next fire stroke going into the exhaust. The fault could be something as simple as a failing spark plug or lead.
