    Setting fork oil level.

    Update #2 5w of Putoline seems like too fast. Need to go to 7.5. 420 cc left me 1cm of travel after i got the rear wheel in the air while braking.

    Setting fork oil level.

    Update, Winter came. The 10w is making the fork to move too slow. Also, i found that with 410cc the fork got bottomed out. I put 420cc of Putoline 5w, looks perfect for mow.

    Setting fork oil level.

    Hi, I want to service my fork soon, i need to check it for myself. I can tell you that after filling 460 of 10w oil, the fork is like a brick. I got out 60ml and i could bottom out the fork by hand. Added 10ml more and seems like the fork is in it's best right now.
