Thanks for the welcome!
No i haven't used any grease for installing them. The O-Ring fell easily in the groove of the cylinder.
I have bought the bike used this year in February with the 144 kit already installed. The guy gave me a lot of o-ring with the bike. (Now i know why).
The O-ring were original packed so i think they should be ok. I never stretched them.
After changing the o-ring the last time, i saw that the coating from the cylinder comes off, right up there were the head fit the cylinder. So maybe the coating wasn't good from the cylinder.
I'm also not happy with the 2 piece head. The new generation of the 144 kit has only a 1 piece head. (no changeable dome)
I think the head doesn't fit that good to the cylinder and the compression is really high (14:1). It seems that the explosion in the head can reach the o-ring. (Maybe in combination with the bad coated cylinder) But that is just speculation.
Athena didn't gave me any feedback to my questions.
I wonder what will happen when i use Hylomar instead of the o-ring?!
greetz!
