Here is the the [EFI] relevant text from a recent (longer) posting by one of Hitchcock's staffHitchcock’s entered a six bike team for this year’s ACU National Rally including three EFi models. One EFi was fitted with a prototype Hitchcock’s big bore 535 conversion. Two EFi’s used Hitchcock’s modified exhausts and a development Dyno-Jet Power Commander ECUs. One engine was also fitted with experimental cams.The route took in fifteen English counties and nineteen check points, with an aggregate total of over 3,600 miles.Six Royal Enfield Bullets, six gold awards and all the special parts performing perfectly.
Thats promising, but I just want someone to make a UCE air filter setup first!
