Derek Hallman Posted April 11, 2010 Okay so this guy has a used Factory Mini 4.1 w/ titanium header and he said it has about 10 mins run time. He wants $230.00 shipped. Or I could buy a new Yoshimura RS2 for $279.99 plus shipping. I have a 2010 KLX110L and the motor is stock. (gonna keep it stock) what is the better pipe in this situation? Also, I dont know much about jetting? Someone want to explain what I will have to do when I get a pipe on? Thanks Share this post Link to post Share on other sites
