I recently upgraded my rockhopper suntour xcr fork to a raidon with air spring. The fork impressed me from the start and was really smooth with great small bump sensitivity. Some couple of months later I started getting some stiction on the fork which killed small bump sentivity. I tried using finsh line dry on the seals and stanchions and I also tried some silicone spray but these measures only seemed to work for a short time, and by the middle of the ride stiction was back. I decided to open it up to see what was up and re oil the foam rings but to my surprise there were no foam ring and no oil. The whole thing was splattered in some type of grease. I decided to clean the grease out and use 15wt oil like the rockshox forks use. I put in some oil soaked foam rings as it had the space where the rings go and added 10 ml of oil to each leg and put it back together.
The fork now works incredibly smooth, even better than when it was new. I took it for a ride today and it felt great. There appear to be no leaks. So my question to you guys is: Will this fork be ok with oil instead of grease or will I kill it prematurely? If there will be no problem, then why does suntour use grease instead of oil?
Thanks four your help!
