I don't know about the Linhai but on the Honda variants it's a mere 180cc. I learned that about the Honda Reflex engine and when I drained mine this past Fall it checked out. My CN-250 engine held a little less than 200cc.

If you can find a 250cc Yamaha Majesty manual somewhere on the web it's the same Linhai engine.

Been a while since I last posted. Put about 300 miles on the scoot here in south jersey .
No problems yet so enjoying the ride. Did the beads in the tires and still get a bad shake at about 55 from the front . Guess I need to replace the stock tires on her.

Took the wheels off and going to have new kenda's mounted and balanced .
Heard good things about these tires.
