I have had my mini chopper for A lil under two weeks. I love it but it's still new to me and have alot of ?'s. I was on miniriders forum but honestly they didn't help me like at all. The sticker on my bike is off so I don't even no wat cc motor I have. It's a loncin and model lc139fmb. It goes about 35 and my carb is pz16. Any help wood be awesome! I'm also lookin for a rear 26 tooth sprocket with 4 bolt holes and a 2 inch bore. Thanks!!
