ok,on my lf200iii gs, i changed the oil (with no help from lifan-forum, china-moto.com,or americanlifan.com), i unbolted the oil drain on the left side of the bike, at the bottom, and drained the oil,
i took out the spring and the screen (gauze) and cleaned them. i slowly pushed kick starter to get all oil out, then reassembled, and with socket wrench and extension, finally managed to get bolt back on, just tight enough to not crack thread. filled with 10-40 valvoline motorcycle oil, pushed kick starter a few times, remeasured, ran bike at speed at or below 30mph, remeasured. runs good!! hope this might help someone, i did get a newer manual off china-moto. com, so i am thankful for that!!
