Harley motor swap - Is this good?

[smartblond48]

My FLCH puked up a piston. Can I replace the engine with the motor out of my son's Baja DR-125 and how much faster will it make the Harley go?

are you kidding ? either replace it with another harley engine, or a S&S would bolt in. anything else would require (most likely) frame and transmission work. And If a Harley guy saw you with a non harley engine, they wouldnt let you play harley games....
