[Diy_efi] Cassandra's relatives: ECU & waste-gate

[Ernest Buckler]

Hi,
I lost track, who owns Cassandra, the CX 500 TC?  Have you yet built an EFI 
& Turbo setup to replace the stock stuff?  A friend and I own a couple of 
these too, and have been wondering what our ECU & Sensor options are, since 
Honda no longer supports these very nifty bikes.   Plus we are having 
continuing problems with the factory wastegate setup - the pivot shaft for 
the blow-off flapper (exit of the turbo) siezes up in the cast-iron, and 
there is no repair cited in the factory manual othen than to replace the 
complete assembly....argh.   1. They are no longer available, and 2. I hate 
replacing an entire assembly just to "repair" a problem that could be fixed 
with a $6 graphite bearing.
