True indeed the founder is right even just after 2 mins my engine will burn the sh!t out of my hand!Ten minutes is a LONG time to let your engine idle. The Chinese two stroke bike engines have no way to cool themselves except for air moving over the cylinder head and cylinder cooling fins. They have no internal cooling fan or shrouding. You need to ride the bike, not let it sit and idle. Heat can damage your engine and with no cooling excess heat is what you'll have.
