Hey everyone, this is my first post here.

I used the search function trying to find my answer but couldn't find what I am looking for. I'm trying to figure out what size jets I need to use? I have cut off my exhaust to dump just before the swingarm (Yes I know it's SUPER loud and SUPER annoying. I just like the look of it. If there was a way to make it quiet and dump there, I would.) I also have switched out the intake to a lunchbox style airfilter with no housing/shrouds. Any help is much appreciated!

Search for "jet matrix".  Find the matrix, and that should give you a starting point. There is no formula for what you need, just trial and error.

Awesome! I'll see if I can't find that.

Haven't seen it on the gs before, but I know someone who has put a cherry bomb exhaust on to end u see the frame. It's not as good as a real exhaust, but better than the a straight cut-pipe.
