Hi my name is David I live in Fort Worth,Texas and I am new to this. I have finished my first build. She is a silver Schwinn Delmar with a 68.5cc slant black X80-BK China girl 2 stroke kit on her. Any feedback is welcome I would like to learn more about how to get more performance out of her. The kit came with a 44T rear sprocket that works well but I do not like the way the sprocket is mounted, also I don't like the chain tensioner any input?
