I have a 07 rk classic with just under 1000 mi on her. I had the stage I done when I bought it and now want to do the stage II 103 upgrade.I researched it on the forum but I was wondering from some of you that have got some miles on the stage II with the 07 motors how its holding up. Any problems/suggestions?

 

Go with the SERT not the PC111. I did the 103 at 500 miles and the thing pinged. Took the PC111 off re dyno and now it runs good.
