22 hp kohler

[newblade]

I am fixing to have to rebuild a 22 hp kohler. Does anyone know how much horsepower will be gained if I bore it out .020 or .010? :cool:

It wont have anymore HP than when it was new.

Why wouldn't you see horsepower gains after you bore it out?

Boring the motor .010 should result in a nice power increase.

Assuming the power increase is proportional to the displacement increase your motor will have 22.14 HP after you're done.

on a new engine and a new engine bored .020 over you won't feel any noticable difference. But you will feel a difference from a worn out engine after a rebuild bored over or not. I find that most engines are running under the rated rpm's so make sure your at the factory high idle speed ussually at least 3600 rpm's
