stock spark arrestor removed?

please help

you will need to re jet after removing. they are lean from the factory.
you will gain a little power .but you will hear the main difference.
some people drill out the plate right behind the sparky for a little more power

can you hit me back with jet info and if you can a pict of where to drill and how big
thanks
