I just got the motor tonight , I was told it was a 4 mill , going to tear it down tomorrow and see , how do I tell if its really a 4 mill and if so does anyone on here know a place to send it to get rebuilt? Trying to get something as cheap as possible (I want to sell this bike after I rebuild )
Also do I have to use a special type of piston , was told the bore was std.( I've never worked with anything but stock before) Thanks for the help
