no it wont the flange is alot smaller on the 50 and the flow of gases would be reduced greatly,find another chinese bike that uses that engine like
baotian,skyway,skyteam,yiben,and many many more just google pictures of the engine and compare thjem they use basically the same engines for most of them.try theinternetbikeshop.com or chinesebikesparesonline.com for parts.
