My 2002 Tomos Targa is extremely loud where the neighbors, well one in particular complained. I dont want it completely silent cuz that noise could potentially save my life by letting others on the road know I'm present. But it really is just wayyyyy loud! I just bought it off someone. Theres a giant hole at the end of the muffler, is something missing? Can I put something on it to quiet it down a bit? Or do I need to get a whole new muffler? And when I start it up, the back tire spins way too fast. I know maybe my carb needs readjusting or can the muffler be the cause of it?
