Hi Kev,
I found someone who translates for me!
The CP piston had a problem with the rings land so I�ve send it back. The bore was bring in the measure of the CP piston, then I used the JE piston without considering the measures just thinking that this pistons suits at the bore OEM (102 mm).
Now the engine stars without problem but I have this movement. I can�t use the XT now due to the snow (about 30 cm here!!!). Did you have the same movement? Do I have to worry?
