Does the B5 have an unique swing arm or does it use the old school arm? 

Along the same lines I wonder how a UCE would run with a flat side carb.

I think everything in the frame is standard old 350 Bullet. I understand they are using OEM spares to build these.

I wonder how a UCE would run with a flat side carb.

Probably not as well as the injection, particularly if you like riding in the mountains.
If you're looking for more power, a bigger carb can help, but it loses some tractability.
I guess then I have to ask you a question. What, exactly, do you mean by "How would it run"? What parameters are you looking for?

  I was thinking bout swapping my 95 motor for a UCE  if I could make it fit..

The chain is on the other side along with the brake. I would guess that the swingarm would be unique to the B5.

To run a carb you would need to find another way to control the engine as half the ECU would be out of service and I don't know how it would react to having parts of it missing.
There is a carbureted model in India. Maybe you could get some one to send you the rotor/sensor and ICU out of one.

Design is same old school but the bushes are different and it might be longer compared to older version. C5 has a longer swing arm by 1  1/2 inch compared to the old ones.

Frame itself is completely redesigned one although it might look the same.

You would need the throttle sensor/complete wiring/TCI ignition module, magneto drum but RE does not sell only the drum so the whole alternator assembly or grind the teethes off the drum to save cost. Also a carburettor of your choice.

You would need to fabricate mounting brackets for the engine to frame and attach arms on the bottom of the frame to fix the engine.

Well,  it certainly would be easier to buy a B5,  but it would be more cost effective if I could get the UCE mill and brake bits for $2500 or so.  Hopefully  I could defray the cost by parting out my 95 engine, primary and transmission.

My guess would be that he crank position sensor would be pretty similar in operation to the AVL as far  as spark is concerned and that the alternator could be made to work with a little research and possibly an aftermarket rectifier.

I was under the assumption that the B5 frame was in fact the same with the exception of mounting brackets.

Crank position sensor on UCE is same as AVL or UCE 350 but the difference on UCE 500 is that it is not used to fire the ignition but tell the ECU the crank position at every 5º(if I am not mistaken) and its firing order is quite weird as UCE 500 fires twice in one complete cycle. Fire once at the power stroke and other at the exhaust stroke which goes waisted.Where as normally we have firing only once in a complete cycle on any RE.

We can use the same setup of existing alternator and crank sensor except the magneto rotor which we can modify but not sure if it can be done effectively. One would need to grind off the trigger points on the rotor and fabricate/implant a longer single trigger on the rotor. If the rotor is not balanced properly then could cause some vibrations too.

Yes agree, could use an aftermarket RR unit with it. Does AVL has a timing sensor hooked up to the accelerator cable?

Or you could just fit a Carberry Enfield V twin
