I have a couple of question: I want to use Zenki 8.5 compression rotors in a BP motor. As far as I know the FD e-shaft should work fine, as far as I know FC and FD are the same. (correct me if me wrong) Will I need to measure clearences differently? What rotor bearings should I use? Plus I am using WPC 2 piece 2mm apex seals, but that shouldn't matter.





I want to beable to run 1.5 or 1.6 that why I want to use zenki rotors?



Thanks in advance guys

So run 1.5, 1.6 on the FD rotors. I told Sean to tell you that you should run what you have. I wouldn't go out of my way to find either. If you use the the zenki rotors there is no difference in bearings, eccentic shafts, apex seals or clearances.
