Engine swap

[1998ck1500]

Hey guys just signed up. I have a project idea i would like some feedback on. I have 1999 400ex with a stock motor unfortunatley the piston melted and came apart in chunks which i assume are floating around the case not sure though. Here is my question I have a complete running 7425 mile 1972 honda cb 450 road bike how difficult would it be to stick it in my quad. I am an ase certified auto mechanic so i am capable but i usually stick to automobiles. any feedback would be appreciated

The hardest part is getting everything lined up, then making new brackets, possibly cutting up your frame, making new exhaust...

But thats really it, if you have the knowledge and the tools or the pocket to pay for it, its not to hard.

Pretty easy actually, if you know how to weld and have acess to benders and drills along with metal.
