Ive had 2 different nice engines over the last 10 years, and ended up selling them when I downsized my mini collection. Both were 127cc “tuned” from asianconcepttha. I picked up a well worn, most likely 20k mile nice 110cc from Thailand. My goal is a simple bare bones rebuild, maybe a few more CC. I plan to split the cases soon, and see what parts I need to order from overseas.
