time for some update
The engine : when I’ve bought the bike it had a 3TB engine fitted. The 3TB stator and stator cover were removed and the 3AJ equivalents were put in place. On the photo below you can see that the 3AJ stator cover was paint in a different (shitty) color.
It is a common modification that I heard about before. The 3TB engine has around 40 kkm on the clock and rather good compression ratio of 1 to 9,5.
Initially I wanted to repaint and keep this engine until I saw another 3AJ engine for sale in France. It had 19kkm. I asked the guy the price, it was 350 € + 70 € for delivery so I told him that I was taking it. I paid and I waited for the delivery.
The day when it arrived to me was a surprise : for me, I was expecting only the engine. The guy didn’t bother to take off the carburetor, starter, etc. So this is what I’ve got :

The complete engine together with all its accessories – even the oil was still there.
When looking at it I saw it had some dust on it but generally it is in a very good nick and I think that 19kkm on the clock is very probable.
So for now, I will be fitting my new 3AJ engine to the bike. The 3TB engine will be there on the shelf waiting for another project…
