cylinder barrel to case fit

(1/2) > >>

Chuck in Indiana:
The Kid is working on his cafe project (No Roper Content).  ;D
It has 1000cc barrels. He said when he tore it down it was really sloppy loose. He's going to call me back with dimensions. He's thinking that everything he has is junk.
As I've mentioned before, I'm no Guzzi mechanic. How should the barrels fit the case?
Edit:
I asked for some dimensions, and he said there was 1/16" slop. There was also a 1/16" shim under the barrels. I *assume* that was to lower compression, for whatever reason. He said the rod bearings were toast, and is wondering if the cause is the barrel to case fit. He's no Guzzi mechanic, either, but he's built a lot of airplane and automotive engines.

What block, round cyl or square. There is plenty of clearance but not that much.
Once it goes on the studs it shouldn't move.
I have some base shims to lower compression but they are around .025"

It's a Frankenblock, I think. Had a spare convert/oil pan block with it,IIRC. It's been a couple of years, and my memory is about as long as my.. oh, never mind..  ;D
Thanks!

Chuck,
If it is the bike you got from me, give me a call. I have cylinder spigot measure
ments.

Dick:
Is it possible it has 850 cylinders sleeved and bored to 1000, but with the original 850 spigot diameter placed in a 1000 case? This would give (roughly) .045'' clearance.
