They actually are LA sleeves but similar, Ill have to watch out for those
Maple syrup overdosing Canadians :)

I planned to fit a g13b crank worked with bike rods and pistons for 79mm
bores with 78mm offset ground stroke (75.5mm+2.5mm) 1529cc.
However a friend is saying I can fit a honda d13 crank and have 81mm stroke
for close to 1588cc once the mains are machined with offset centres for better
powerstroke and less rod angle.

Chris Ive had an alloy peugeot block posted from Chile which was 19kg without
sleeves but heavier block than the suzi g13b.
