I have a bone stock Mitsubishi 49cc motor, and am looking for all possible upgrades. I've researched and all I have found are xcan exhausts and a 15mm intake. I can do a little fabrication, but not a lot, so my question is, are there any other upgrades? Preferably a big bore?? Something that will give me a lot more hp (im talking at least 2 more hp)
EDIT: I was also curious as to what an expansion chamber does to create more HP
