Without stroke dimension its impossible to answer!

[Danielson]

Should be able to tell by the size of the barrel.  72 mm is 1074cc

If we are talking about a 16 valve GSX1100 it has 66mm stroke. Then 74.5mm cylinder bore results 1151cc.

You still need thre stroke of the engine to determine the actual swept volume…..

even a clue as to what model / age your talking about would help people help you
