Is it a VH or an RH500. The answer is yes to both. Bikes which left the factory with RH500 on the timing covers were listed in the Despatch Books as model VH. Quite when they changed the timing cover from RH500 to VH I don't know but it would be no surprise if the RH500 cover was original for this bike.
