How to identify 103 motor vs 96

The only difference will be the bore size. All the components except pistons rings and wristpin are the same. I cant think of a way to externally verify that it is a 103.
However, the ECM should be tuned in some fashion for a 103. It should have a custom tune of some fashion or a factory tune for the 103. A 103 engine with a stock 96 tune would run quite lean and likely cause premature engine damage. I would have the moco look at the ECM calibration or ask him how it is calibrated for the 103.

As previosly stated, start with the vin. If it says 103 you should be good.
If not:
1- It should have compression releases but not necessarily if its a 103. Was it a factory 103? It just depends on what kit was installed. Compression releases are highly recommended but some people dont. Furthermore, just because it has compression releases dont mean its a 103. Some folks stay with stock bore and put ported and polished heads and cams and install ACRs.
2- Look at the ECM Map it will tell you what the bike has in it assuming the installer installed a map with the kit.
