Hi Alfonso,
I just checked the entry list for the 200mm Euros at your home track next week, but I didn't see yur name. What's up? Are you not racing?
Sabrina Lechner, Reto Koenig (Burito) and Dirk Stammler from our team are going to Madrid.
Do me a favor, go by and say hello from me
Take care,
Stefan

A 'C' and 'F' plugs protrude the same on the combustion chamber, so the compression could not be different between them.
Being conical at the end of the combustion chamber, you cannot insert more the plug unless you do a gorilla tighten and break the plug button or strip the treads.
