Ok guys here's my question, I got a stealer putting on a new warranty rear shock and got to talking about carb sync, poping and rk muffs. He's telling me I HAVE to rejet the carbs and I am looking at 300 - 350 to have it done. Pretty sure I read many post about rk muffs and NOT re jetting, so I guess I am looking for your opinions?
road king muff's to rejet or not?
