Is it possible to convert a 85 lt250r motor to a power valve motor? I imagine not since no one has talked about it. I wish I had bought an 87-up and was wondering if I could convert mine over by putting a newer top end on the crankcase. This may be a stupid question I am still learning about these machines.

 

No the jugs will not interchange,it would be easier to just buy a whole 87-92 motor and swap it but youll have to do some frame welding
