Hadn't used my Gargoyle since fall. I fancy using quite hard valve springs in the summer so I needed to change that out.
Buddy of mine was using a Phantom and also had to change springs because of the cold.
After changing my spring while finishing my coffee, and Chronoing. I asked him if he needed help getting his Phantom back together...
Unfortunately all I brought with me were cocker valve springs (and no 12ies with me) so I wasn't able to test the winter valve insert like I wanted to during lunch break. Hopefully I can do that for you guys and have some numbers to you by this time next week.
