.........Plus, whatever you do to "turn the fork over" is going to involve removing the fork legs anyway...........
There seem to be a lot of questions. I know the original is a REALLY long post but please read it. Then read it again. Then leave it for a day, then go read it a third time. There's a lot of info there but it's all there. Take the time to read and absorb it.
195ml is perfect. Synthetic is less affected by cold temps. Forks tend to feel stiffer in very cold tempsas the oil gets thicker. Synthetic oil gets thicker when it's cold, but not as much as Dino oils. And it lasts a little longer. The advantages are not enough to pick it over the proper weight dino oil, go with regular if you can't get 10w synth. I put 5w in my fork and moved the leg, you could barely feel any damping. I'm a fan if light damping but that was almost none at all. Going heavier means the fork will be less reactive and will transmit more shock to your hands. It may stop the initial dive a bit on braking but an extended stop will push the forks down just as far. IMO heavier fork oil is usually a cheat that covers problems that should be fixed another way, usually more preload or stiffer springs. Just go with 195ml of 10w in each leg, you'll be amazed at the difference. If you doubt it, check Barenekd's recent post. He rides hard, pushing the bike to the limit and beyond. The right amount of 10w oil made his bike feel way better. Scott
Or, he might just move to the southern hemisphere ...... that would flip the whole bike over !
Any name brand 10W fork oil should do just fine.
