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.
Sorry again for the delayed reply. As a result of a small percentage of failures due my assumption that a well made item would fit on every crankshaft - which turns out not to be the case - I have had to re think the job. I recommend that, If you have one of my kits waiting to be fitted, then you should bring it to me or find a properly skilled mechanical fitter to install it for you - that person may find that the fit is not good enough in which case you should contact me for a solution in the form of an undersized hub to fit your shaft. whoever is fitting the hub to your shaft should look here for a description of the process
https://www.youtube.com/watch?v=UAnLJGKJDsM Please do not make the assumption that if it feels tight going on that it will be OK - you must inspect the splines carefully to see marks where it fits tightly especially on the flanks of the splines - this will require pulling it on and off several times - tedious but there is no safe alternative. As always I am here for advice please feel free to get in touch although I don't spend much time on these pages so a mail or phone call would be better.
