Just noticed by chance on PB website that Phil is no longer offering the full Centa conversion unless its hand fitted by himself to the engine at his Lancaster workshop....
Phil is now only offering the PB inner rotor upgrade option as a third party/non UK fit option (unless you ship the engine direct).
I have actually only been fitting our own modified inner rotor and not the full Centa for past 4 months due to the issues with the PB Centa/crankshaft fit.
So if you have a PB Centa kit waiting to be fitted by a third party then your choice but I for one would just go for changing the inner rotor and leaving the original outer Centa in place attached to the crankshaft.
That is what I did, since the rear crank seal was not leaking oil I figured why mess with it.
