The big bore kit is a conversion for the standard 2CV6 engine (602CC) and brings the cylinder volume to 652cc with a compression ratio of 9/1. This results in more power and torque. The tolerances on the dimensions of the piston and the cylinder are well within the original specifications of Citroën. The cylinders are new castings, they are not a bored out old cylinders. The applied cross-hatch hone pattern is optimized for this use, and applied by machine. The kit comes with the pistons and rings allready fitted, and with jets for the carburettor. The jets are specifically for the double barrel Solex 2CV carburettor. The venture sizes of this carburettor are 26mm and 18mm (marked on the side of the carburettor).
This cylinder kit needs to be run in. We advice you to not drive faster than 80 km/h or 4.000 rpm for the first 2.000 kms. After this period, steadily increase your speed. Only after a carefull run-in period will your engine reach it's full power potential.
