No trying to hijack, but I'm having similar issues. Also had a cacyclwerks pump in the bike already.

I finally gave up after having the bike apart three times and still not being able to determine the issues. On one of the tear downs I noticed that one of the in tank fuel lines was compromised, ie it was split. At the time I assumed that I had done this when tearing the bike apart.
Fast forward. I take the bike to the dealer as I'm flummoxed. Dealer says fuel pump. I ordered another cacyclewerks pump (130 beats the heck out of 500+ for the OEM fuel pump kit). Dealer installs and the bike starts no problem. Yesterday I took her out for a shake down run and sure enough coming off of a stoplight the bike loses power. Get a nice local guy in a truck to get me home, pull the regulator and sure enough one of the hoses is split open. Could it be that the pressure regulator isn't working and the pump is putting out too much pressure? Seems questionable that it'd be able to put out that much pressure to split a FI rated line. Since the new pump has been installed the bike seems to be idling high. I haven't touched the idle screw, but wondering if a build up in pressure is forcing extra fuel into the throttle body.
On my way down to Tennessee this weekend for a camp/ride and I'll bring more fuel line as I don't have time to get a new regulator if in fact that's the issue. Just not looking forward to trail side repairs if this problem continues.
