Newer engine will require it's own electrical installation ECU and more stuff that eventually it will probably cost you more than to by a newer bike.And all that after making sure that the pin holes of the new engine fits the pin holes in your frame.Needs a lot of work and money.

Why is my engine makin a knockin sound

This problem sounds like your lower crankshaft bearing is worn.
the only way to be sure is to pull the top end to expose the rod and center it and see if it has noticeable movement up and down play.
If the crank needs rebuilding make sure you also replace the main bearings
and new seal kit,piston and rings Etc.

I do also need a new engine,

you probably blew a gasket, any engine is repairable and rebuild-able but if you want the easy and quick way.... go to a salvage yard.

Engine rebuild

Take it a part and do it right or you will only tear it up worse when you clean it and get it running again.

250cc engine

250cc engines vary on size and design by make and model. It is possible to put on in however you will have to make a bunch of modifications and possibly make some new engine mounts and on top of that it may not be a Kawasaki motor tha ends up fitting. For the difference in power its not really worth the hassle unless you are on an adventure..
