    JC50 are based from '78 model http://www.moto8.net/thread-77245-1-1.html
    Genuine parts from JC + KOK seal http://item.taobao.com/item.htm?id=10662398973 According to that page, it seems some <90cc valve that based on horizontal Honda also fits.
    Measure & compare. 5.5 or 5.0 ??? http://www.tkrj.co.jp/product/m-engine-valve.html. http://www.ycpiston.com.tw/p5-11.html
