hey pace, had 7871km at start of 2nd BBK, has 10014km now, that's 1329miles. I am not riding it now, still working on installing Malossi carb. Sorry I am so slow, had bad cold for 2 weeks, now have another issue that keeps me from working on it. I am riding my S9's for now.
I have 2 sets of Malossi gears, 6711055 and 6711802. Neither set fits People 50 2T, don't know about Super 9 LC yet, haven't disassembled to check. 6711802 is supposed to fit Super 9 LC, but I would not bet that it does. 6711055 may fit Super 9 AC, but I don't know, only way to know is to physically check, my experience: Malossi info about product or web search is not reliable.
If you get Super 9 LC, will like it, I have really been enjoying mine recently, 49cc LC runs pretty strong, much better than 49cc AC engine IMO. Cheers
