Syxmoto minidirtbike

Been a while since I logged in to pocket bike planet. I've acquired a few x1 pocket bikes and bicycle motor kits in the last few years and had pretty good luck at making them faster with modding the engines. Port work like polishing the exhaust and port matching along with changing the squish gap and playing with pipe resonance has yielded decent gains. A member who went by cam2 laid the foundation for me and I have completed a handful of good pocketbike upgrades. Recently a buddy gave me a syxmoto 50cc 2 stroke minidirtbike to experiment with. Rebuilt the engine with a big bore kit and fitted a racing carb along with the above port work and brought it back to life. Haven't yet changed out the pipe or worked on the suspension, I wanted to see if anyone else on here has any experience with modding these? Its a fun little bike and any ideas or suggestions would be greatly appreciated. Btw, cam2 if you are still on this forum, thank you for all the tutelage several years ago.
