The problem with any component out of China is getting hold of useful tech info about it.
Even 'which wire connects to what' level stuff.
My bike mech mate, Pete Allica, ran up against this issue a few weeks back, when looking to replace the ignition module on a Chinese made quad bike - IIRC either the bike or the replacement module was a Lifan.
He did however find a source for that info - but I can't ask him for details just now, as he's over in China for another week.
