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!
Bottom end is good enough but the connecting rod bottom bearing has to much axial play to start with, resulting in few other issues. I could be wrong though. Q for Experts, how much axial play in con rod is acceptable? UCE con rod has .20 axial play to start with and I am not comfortable to start with.
A small amount of axial(side to side) play is normal, and is present on all Bullets. Actually we see up to 4mm of axial play quite normally on the older engines.Any perceptible radial play(up and down) is unacceptable.
Ace: I think SSR has units in inches, because 0.20 inch equals 5.08 mm which is a little more than what you saw (4 mm).
Its not listed on the manufacturers US website and is listed as "temporarily un available" on Mr.H's website.Still watching and waiting.In the meantime there is always this,,http://www.straightlineperformance.com/catalog/index.php?cPath=221&osCsid=e5f0b349a9784caedf4ba44d0214ec3c
