Thanks Patrick. I appreciate your shoutout. :D


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

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

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.
