Hi.
Frame wise, (and body panel wise) I think the B 5 is actually the same as the Indian model traditional 350: I am not sure if this shares a common frame with the iron barrel or not, but though the Nfield gear website doesn't yet list it as a separate model for parts search, I think you will find a wealth of low cost aftermarket parts for the 350 on the Indian site, and there is no reason these wouldn't fit the B 5 (other than drive train which is of course the same as G 5 C 5.
The G 5 frame is from the Electra a mid 1950's iteration , and it's larger wheels and slightly grater trail would lend it better high speed highway performance.
The C 5 has 18 inch wheels a longer swing arm and smaller rake/trail coming out to almost or exactly the same wheelbase but as a result has better low speed handling characteristics (which is not so say that the G 5 is a low speed slouch)
The B 5 is the frame /body that has earned Royal Enfields the deserved reputation of tough overland traveller > I believe Scooter Bob indicated (to an earlier question) that the steerring head may have the traditional loose pack bearings instead of manufactured raceways, but that it was in other respects the mechanical equivalent of either C 5 or G 5 . Also , attached below, find a reply from Hitchcocks to my enquiry a few months ago about the status of their performance mods, which would be applicable to any of the three. Cheers, Nigel

UCE Performance Mods Heads Up
« on: March 24, 2011, 05:58:27 PM »
--------------------------------------------------------------------------------
Seeing that Hitchcock's has a whole "suite" of performance mods available (though at quite a price---about 1,900 pounds , not dollars) available for the Iron Barrel, out of curiosity I asked them what they had up their sleeve regarding the UCE. Copied below is their reply. In their website they seem to quoting similar hp improvements to those achieved by ACE in the Fireball package this side of the Atlantic, though part of their package is a stroke change and displacepent upgrade to 612 cc (Bore 87 think) :
The gent that corresponded did wish to correct the statement regarding programmable setting intervals on the power commander : Not 200RPM as stated, but 250. His response also seems to answer some of the questions that were being tossed around in previous threads on this forum regarding the interaction of the stock CPU for the EFI and the Power Commander in widely modified engine breathing/capacity situations. (ie looks like the undertaking can be accomplished with the stock CPU overridden by Power Commander specially scripted to the performance specs of the modified engine. I don't know if their head mods are as extensive as those in the Fireball project.
Anyway, for those who are interested in this or already involved in this work, I thought you might like to know their agenda. Regards Nigel (Please remember that I am not technically sophisticated so apologies if the terms I use aren't professional lingo. I just try to explain it the way I understand it.

Oops, fogot the attachment
Hi Nigel,
We are slowing working on a 612cc kit for the UCE model (we call them EFI over here), a head and cams will be part of this kit along with bigbore kit and crank. However although we have been developing and testing for about 18 months, it is not expected to be available until the end of the year.
We already have a 535cc piston for the EFI, this is a German made forged piston under part number 90224 @ £140.00 which works well with the standard bottom end.
We can offer a K&N air filter element for the Electra EFI, but not the classic EFI.
With anything other than a basic silencer change you will need the power commander as the standard CPU does not have enough range. We have used the power commander on totally stock engines and had improved running. We normally program these for the customer from a number of maps that we have available depending on the specifics of the modifications. Alternatively we can supply all these on a disc with the power commander if the end customer knows what to do. If you have a decent understanding of these units you can also manually change the mapping at 200 rev intervals. As we develop more parts an increased range of maps will be available.
