I bought the bike with the baffle cut out of the stock pipe. Just ordered a Dyna muffler and have new jets comming this week 155.5/52.5 Running the stock airbox right now but depending on how it runs with the new jets, I may go to a K&N side mount. I want to move the battery back a bit.
I should start a build thread I suppose rather than necro this one. But when I was searching for anything on a 230 main jet, this popped up. Be on the lookout for my own build thread.
