Thanks to The Great Stinky. That site has the belt I need at the best price. I can get an Aramid fiber belt for less that other places want for a cheapy belt. Thanks again!

Now to find one of those non-smog motors.

I was at a Powersports shop asking them about scooter tires. They had Michelin 110/90/10 for about $50. They said the Michelin last about 6,000 to 7,000 miles.
One of my scooters with 10" tires has Duro. These tires have lasted me just under 6,000 miles and I brake REAL HARD.

I've broken in some Honda and Kawasaki road bikes. When I was a teenager, my Dad, brother and me all bought identical Honda CB750's. All 3 were broken in different.
My Dad and me broke ours in kinda normal, just riding it like I normally would gentle throttle on take off, but no hot rodding it. Once in a while I would get on the throttle but not wide open and no high revs. That bike lasted me about 12 years without any engine issues. After break-in period, I would rev this thing high and go speeding around.
My brother thought break-in meant go WOT and rev like crazy. His bike had some pretty serious issues after about 1 year. Valves went bad, rings went bad and crank bearing had to be replaced (1 broke).
My opinion on break-in, ride it normally (NO HOT RODDING), ease on the throttle (no WOT), gently go up and down in speed and change the oil after 100 miles. Change oil again at 300 miles.

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.

I've been looking for street/trail tires for scooters. They are not full knobbies. I had these on a couple of street/trail bikes and I liked them. No luck in finding any though.
