I have just fitted a power commander V to my Versys '07. It is running with the supplied map and standard muffler, although it has a DNA air filter element now. I notice the pick up is markedly better, although shuddering (like cam knock) in the rev range has now moved from about 3500-4000Rpm to higher up ie: 4500-5000rpm, which is right when I am cruising at about 100Km/hr. What would be your recommendation as I have not as yet changed to any other maps?
Thanking you in advance.
I live in Australia and own a 2012 ZX10R. I just purchased a PCV from a US based website called Motostarz. I also purchased an Akrapovic slip on with titanium link pipe. After making these purchases I found out that there is possibly a difference in US and Australian PCV's. Can you please clarify this and also where I can purchase the correct O2 Optimiser for an Australian ZX10R.
