Cant do big bore kit on the 6cyl wing motor. Not much room between the cylinders to start with.
The new 2018 motors had a bigger bore but smaller stroke. To cut some weight off the top end.
Would have to have a bigger block all together.
But I would like to see a 1800 bobber!
Here is one.

the guy who invented the second one... he was the genius!
