Re: No wonder these motors are so cheap!
I have a PK 80 ready to go on my board tracker style bike. the 50 cc i use now on another bike is good. I think it is just luck if you get a good motor or a bad one! They are ALL built so inexpensive that it is like the lottery, win some lose some, but you can't win if you don't play! I am proud to live in AMERICA too Toker !
