I have reviewed all of the mods articles and have a few stupid questions: I believe with my limited mechanical ability I can complete the following by myself: remove exhaust baffle and grey wire. Does it make sense to do these changes without doing the others? Will this increase the performance? What about if I only remove the exhaust baffle? Second question: Are these changes bad for the bike? A friend suggested not to make the changes due to Yamaha designing the bikes components to work together - tampering with them will throw things out of sink. Thanks for your help - I apologize in advance if these questions are covered elsewhere.
