    200x/200s head/valve interchange

    I finely found a nice 200x I could afford. Problem is it has low compression. I got the motor tore down today and found out it has a bent intake valve There are obvious signs of piston to valve contact. I think thats from the very loose timing chain. My question is do the 200s heads work on the 200x? my 200x is a 84 and the motor i want to use the head from is a 84 as well. If the whole head wont work will the valves?

    i heard that the heads are interchangeable but the cooling fins on the x are larger so if you put a s head on a x motor the cooling fins will be smaller and look a little awkward i dont know if its true its just what i heard
    good luck and with a little tlc that x will be a nice bike

    Mine tends to be the kitchen table with my moms goods towels for rags, she hates it. But she helps me sometime, she rewound my recoil spring when it popped out and helped me put it back in.
