The KTM's can really benefit from the carb boring modification....

I've got two Pro KTM carbs right now I'm doing.......

Thanks again.

Do you have to change jet sizes if you bore your carb to (43mm)??

And if so, what would be a good starting point?

Thanks

assuming you have other mods like an exhaust, cam, porting etc. you would bump up your main jet. I run a 172 main or somewhere around there, along with a 48 pilot.
