Default Re: Drilling the muffler+Air Cover Mods

Mine came with a black cap muffler(the one that just the bottom cap comes off).
I took off the end cap and drilled the 2 smaller holes larger and also drilled another 3rd hole next to the 2 small ones, then i put cap back on. Works good but also a little more noise. For the aircleaner housing just a couple of extra holes will be fine(dont make them on the top of aircleaner or water might get in).
