G'day man and welcome to MBc.
My general rule of thumb is 36cm(14") measured from the INSIDE of the triangular frame from the crank to the seat.You can go slightly smaller but it's really not recommended cos there's always routine maintenance to do.You can also get a smaller sparkplug if necessary(Champion CJ7Y)
You can also grind the engine down and have aluminium brackets welded to it but that's another story.
