I am now rebuilding engine in my UL project. Now when cylinders are out
I noticed that they are sleeved to STD size (no new sleeving but driven
with that setup).
Bore is shiny with small vertical marks from piston travel.
But the sleeve size bothers me. It is about 3.5" (89mm) OD and there
can't be lot original casting around it. Is this normal dimensioned setup
or is this too big risk-taking...sleeve has flange in upper edge.
Cylinders are original 11 fin 1200cc UL.
