I just picked up a 2011 Tomos Streetmate R and it is in need of a new carb and exhaust. This is decent news for me as I realize these are some of the most common replacements to get more performance. I also want to replace the back sprocket and air filter to gain performance. If anyone could help me pick out parts that would be great as I do not really know what kind of parts I should get, links are great!! Thanks for your time!
