Bill-
My 77B has a DGV fitted. It was a replacement for a single Z-S, and most
definitely is a HUGE improvement over that P.O.S.
Had I knew then what I know now, I would have seriously considered a dual
S.U. setup. The cost of the DGV conversion is less than a set of new SU's,
and it is a bit easier on the maintenence side of the ledger.
I feel that with my engine - 9:1 C.R., Piper Cam, European spec 45D dizzy,
that the difference between the Weber and the S.U.'s is probably
negligible - although that is not based on any real life experience.
Regards,
Chris
