Hi guys I have a 1997 yamaha sr 125 custom model and am intertested in giving it a little performance tweek just to get a little more out of it! I can get about 60 MPH out of her on a good dan and acceleration isnĀ“t really a problem but just want a bit more! I do have some knowledge of bikes but never upgrading them! Where is first place to start. Already got iridian NGK sparks and allbright zeon bulbs! New cables! Want a new air filter but not sure which one will fit best and also maybe a bigger carb or piston bore kit!!! Is it possible for this bike? Also would like a new exhaust to make at sound a little different! If someone can give me some ideas and links it would be great! Many thanks! Dan
