my friend had a YSR50 in 1991 (the YSR50 is a street legal pocket crotch rocket, had a 49cc two stroke, 5 spd, 12 inch wheels and full fairings) in which he installed a water cooled YZ490 motor. He stretched the swingarm NINE INCHES and still had to lay over the gas tank to keep the front wheel on the ground. I bought the bike from him in 1999 (YZ490 motor long gone) and my friend sold that custom swingarm on ebay lol.
