All I have is the motor and not 100% sure on what I have now. The cylinder has EC45PL-01 on it. Does that help to ID it?? I ask because I have the motor and a set of SLP twins for a 95-96 xcr440 sp. And im now wondering if they are right and worth putting on. What size carbs did the xcr 440 sp come with. I already put the 34's on that I have but i now dont know what I should do.
