Big bore kits for a Z1100A1 ???

I know the Z1100A1 (shaft drive) engine is based on the 998cc Z1000J, but what size will the standard liners go out to :roll:

I'm sure the crankshaft has 18mm wrist pin size, and am looking at a 1135cc MTC piston kit but don't want to have to resleeve and bore the top crankcase out.

Thanks, Will

Cylinder bore only.

link to mtc pdf , says they come as 17mm wrist pins, but can be honed to 18mm ?

Whether you have 17 or 18mm pistons, depends on the model year. There are Z1100STs that have a classic J bottom end and some that already have the later UT crank (83 onwards IIRC)

Cheers,
