Hi Steve,

I've never heard of a difference in 1000 cc jugs. Whole thing should be a straight swap.

HOWSOMEVER, there was one (or a couple?) year that Harley, don't ask me why, made an 1100 cc. These are probably the jugs in question. Dunno what the difference is.

Luck,

I'll be damned! Didn't know that.

How 'bout plugging and re-drilling the holes in the head? This was often done to put Pan jugs on a Knuck - one hole was off. Easy job.

There is also the option of sleeving the cylinders, which is the way I'd probably go. Any comprntent machine shop can do it.

Hang in,

You also gotta make sure you get the right head and base gaskets to use with the 72 due to the change in oil passage placement and dont use late 72 gaskets on a early 73 either

With the odd head bolt pattern, he shouldn't have any trouble except for finding the gaskets.

Need to watch it - there's nothing like a loaded up top end for foging mosquitos!
