Was there an answer to the question from Michael which was posted in July 2005 he asked "the engine is a copy of the Honda 250 rebel with 26 HK. But the JL250-5 has only 17-18 HK. How do I get the extra HK out of the engine." I have just bought a Jinlun JL 250-5 does anyone know where I can purchase a mainteance manual ( in English) or which Honda Rebel engine the Jinlun 250 is based on?
