I have a Yamaha rxz135 engine I'm working on, the stock piston used is a 56mm, domed, longer in length (slightly) while the new Piston 62mm is shorter in length and has lesser dome than the stock piston, also uses a thicker 2nd Ring. I wonder how big of a difference will it make if the New 62mm Piston is used considering the dome, height, ring differences between the 2?
Left is the old (Stock) 56mm Piston, right is the new 62mm with less height and dome.
