Some tips.
Air filters are about $5.00. Buy a couple (have one for a spare). Spray WD-40 on the foam filter element and clean it about 1,000 miles (depends on where you drive & how much dust). You can clean the filter by soaking in a small amount of gas, then let THOROUGHLY dry. Reapply the WD-40.
Spark plugs cost about $3.50. Again buy a couple. For a 139QMB I use NGK CR7HSA. Gap about .022".
Check tire pressure often. Fill to the amount stated on tire. Under-inflated tires are a bad thing and they wear too fast.
Change the engine oil and the rear end lube regularly. Rear end lube use 75W90 gear lube.
Check valve lash occasionally (not that hard to do). Set valve lash at .002" - .003".
Keep your gas fresh and change fuel filter (1,000 to 1,500 miles). If the scooter sits for a while in the winter use either Sta-bil or seafoam in the gas. Alcohol (Ethanol) in gas can gunk things up. Use Seafoam to keep the fuel system clean.
Adjust and clean the carb a couple times a year. Set idle. Make sure it is not running lean (lean kills engines, too much heat). Always err to the rich side.
Check your CVT belt. Make sure it has no cracks or excessive wear.

With periodic maintenance your engine should last a long time. I have a 139QMB with over 4,000 miles on it (3,000 last year alone). It doesn't use, leak or burn oil. It starts well even in extreme cold( -5*F). It may not be the prettiest scooter in the world, but I know when I push the starter button it will start and I'm riding.
