You just have to grind the caps off, ream them out, and press new caps on that come with the kit.
But also do all the drillings specified in the kit.
The tiny original drilling as almost microscopic, and much too easily clogged up.

The PROBLEM with the 09G is when the valve body gets clogged and you hear the whining sound of slipping.
That is when you have to stop driving it.
