what a pain!

This is very doable the real problems are that cylinder and head bolt
pattern and water jackets have some basic differences between the 1100
and the 1200, So mixing and matching of parts can be problematic when
mixing top and bottom ends.

The one thing I was concerned is whether the carbs would be spaced apart
the right amount for the gpz airbox, and whether they would be the right
height. There's always pods.

times and

deliver after

	So the ZRX1200 motor is a straight swap? Don't have to worry
	moving anything over to it? Man, this sounds like the way to go,
if you
	ask me.
