Check your tire air pressure at least once a week and before long trips. Be sure to use an accurate pressure gauge. -Check your air pressure when the tires are cold. The tires are cold when your motorcycle has been ridden less than a mile at moderate speed or after being stopped for three or more hours. -If you must add air when your tires are hot, add four pounds per square inch (4 psi)(28 kPa) above the recommended cold inflation pressure. Recheck the inflation pressure when the tire is cold. -Never release air from a hot tire in order to reach the recommended cold tire pressure. -Normal riding causes tires to run hotter and inflation pressure to increase. If you release air when your tires are hot, you may dangerously under inflate your tires. -If your tires lose more than two pounds per square inch (2 psi)(14 kPa) per month, the tire, the valve, or wheel may be damaged. Consult your local dealer for an inspection. -Use valve caps to keep valve cores clean, clear of debris and to help guard against air leakage.

There seems little you can do other than ensure the ignition switch is working and actually connecting the ignition unit to the power source, the trigger coil has continuity and the ground and other connections are sound. If all seems ok then replacing the ignition unit seems the obvious next step, though the dealer would probably be able to test the original before you spend money. https://www.google.com/search?q=2006+tomos+arrow+r+ignition+system&rlz=1C1CAFB_enGB673GB676&sxsrf=ALeKk00WgzwxARbeNUObma1FgkzIp64ssw:1592538215569&tbm=isch&source=iu&ictx=1&fir=isM5k54m5RXJYM%253A%252CoekicJg1CPsSVM%252C_&vet=1&usg=AI4_-kReIi-aijzMM7Xnd5wv8-UBIkj9eQ&sa=X&ved=2ahUKEwiK9YSV-4zqAhUxVBUIHSN_BtMQ9QEwAHoECAcQBQ&biw=1366&bih=657#imgrc=JnrXX4E33vyv7M
