To get 1100cc you need a bore of 80.8mm against a standard bore of 79mm

The bottom of the liner is pretty thin, I've got a 1050 liner in the garage somewhere, I'll dig it out and have a measure but from memory I don't think there's enough metal there to bore and hone to 80.8mm

You could make some larger diameter custom liners and get them nikasil plated but you'd then have to machine the upper crankcase for the larger liners, potentially compromising the structural integrity of the upper case and find someone to make you a custom head gasket.

Larger pistons shouldn't be a problem, JE still have the drawings for the custom 955 Daytona pistons they made for me. I could probably get an oversize set made...

The question is whether the cost outlay is worth the power gains.
