Theres this kid that I met today after getting off work. He also owns a MB and says that he gutted the muffler completly and hence that gives him more speed and torque. my question is, is that healthy for our China girls? I mean if you think about it, that would be pretty much like an expansion chamber without the end...so it seemed plausible. Finally, What about plugging a headlight onto the white wire of the engine?? I feel that is extra work for the magneto, but I do ALOT of riding at night and so its something I've been thinking about. And is it possible to also hook up a tail light as well?? I was thinking of plugging in the headlight and rigging a switch to it, that way it would only be on when I need it on, same with the tail light. I hope someone can shed some light on this. Thanks!
