Valve adjustment/inspection should be done at 1,000 miles or so. A 50cc GY6 only has a clearance of .002 inch to start with and can use that up pretty quickly. After the initial adjustment it will go another 2,000 miles before needing a look at an may just be holding fine.

It is a common myth that a brand name scooter will outlast a Chinese 50cc but it isn't so. The 50cc GY6 was originally designed at 80cc and was debored to 50cc since it was a more common size. Many of the 50cc scooters are going outrageous mileages and running strong.

Several years ago I saw a picture of a two-year-old Bintelli 50cc with 20,000 miles on the clock and running strong. Three years ago I also saw a story of a young man with zero mechanical finesse riding a used Bintelli Scorch 50cc from Michigan to Key West with no breakdowns. The Chinese have virtually taken over the 50cc market and brand name offerings are slowly disappearing as a result.

Don't worry that it's Chinese and enjoy the ride. It will be running for a good, long time.

Great advice!!! Thank You!!! I will have the belt checked. I also think I bought a good scooter! I was told that JiaJue is also part of Brintelli??

When I drive the scooter it accelerates strong and gets up to 40+ mph easily with no chugging, ticking or weird noises.

I was told that not having issues, especially when getting near 40 mph is an indication of no issues with the belt because IF I had issues it would not accelerate easily and I would hear or feel the belt under my feet, and my scooter would be a bit sluggish which it is not.

so, My plan is to check it soon, and when I get near 1200 mi get the brakes done and have the scooter rechecked and replace what's needed. It has so far been a great scooter and changing the spark plug 2 weeks ago really revived how well it runs, starts and even idles. So glad I did that!
