Had a Centa fitted to replace my original Harley style compensator (that always worked really well on my car and no problems after 5200 miles) when the chassis was changed last October.
Have to say that the car feels quite different and I preferred the old device in terms of driving pleasure. Not helped by reduced engine power thanks to fan upgrade etc.! Oh well...
Anyway, question is - can I tell if it has the new innards or is it simply a question of what was available / lying around at the time? Was there a definite date from which all new Centa units will be the ones with the bigger rubber bits??
