I am currently working on a KDX 50 .. I want to replace top end .. I have some JR 50 parts , they look the same , carb , gaskets , ect. Both bikes look identical .... websites advertise that parts fit Suzuki JR 50 . My question to is to anybody that has expertise , or first hand knowledge about this ... Will the top end parts interchange ?? Suzuki parts are , almost half price compared to Kawasaki . Thanks in advance ....
