Hi all

Anyone got a zx10r engine just need some measurements if possible,

For exhaust port diameter (ID) and what the hole centres are between ports,

Thanks for any help

Any excuse to jump into the garage - will have a look now.

Its a 2005 engine if that's ok?

42.4mm ID of exhaust port
82mm hole centres between ports

Perfect thanks for your assistance, and at least it's not too cold tonight
