Yup, I thought the same thing about the RPM increase -- why mess with pink wire, if all it does is raise the limiter...
But after having done the p/w mod, I am almost sure it does something else (definately feels like it changes ignition timing).There's a more agressive hit, even keeping away from the limiter. With the heavier valve springs I'm using now (from the Kibblewhite kit) it feels like the p/w mod helped get some of that hit back that I felt the bike lost from the springs. I'd be a little wary about trying the p/w mod on stock springs. Might be ok, but I'm thinking the heavy Kibble springs have a better chance fighting against valve float, should for some reason I hit the now higher limiter (maybe while revving to bring the nose up, during a jump?)
It seems a good combination for my setup. But I don't tend to wind it out as long as the guys on tv do. (you hear rev limiters quite a bit on tv!) I don't have that factory mechanic (or parts budget) just waiting for me to pack it up for the weekend so the top end can get a rebuild.
