By your own admission, you have no idea what you're doing. And if that's the case, take it to a shop. Either that or spend the summer on here trying to figure out why your bike runs like s*** when you should be riding. Or go ahead and try it and i'll be watching for your future posts. If you just want to sound cool, do a holesaw mod. You'll get the same effect and not have to molest the bike and spend a bunch of money to get it. BTW, have you chosen your earplugs yet?
