Taking the engine apart

The engine come apart like any other solex, I usually start by removing the carburator, fuel pump, crank case cover, and the cylinder.

I then take care of the crank shaft side with the flywheel, then the first obstacle on this bike was the coils, since they are smaller in length but chunkier, the Solex tool would not work and I had to be creative since it's easy to bend the plate.

I solved that by using out of order 3800 coils and pulled and it came out eventually. Then comes the clutch

Which is different from the 3800 as the springs are longer. It was the first generation of clutches on a Solex since all previous models (1400 and prior) did not have any.

The crank shaft, the spacers and bearing came out next

Here is the dirty crank case
