On youtube the closest post I can find about rebuilding rear motorcycle shocks is titled How to Rebuild Motorcycle Shocks (coil over strutts). This is not for Cerianis. Ok I have the sf and sf II rear shocks which look the same. Top has 2 rings below mount. Bigger ring on bottom. Top ring has the cut. Ok on the bottom of shock up side down it looks like there is some kind of a big clip inside. Do Ceriani rear shocks come apart from top or bottom? Then what tools and how to progress?
Then the sf front forks (which turned out to be 35mm which Laverda did Not have in the manual for the seals anyway, they are 38x50x7 in the manual) are ready to go on. In the manual it says 200mm measurement in a test tube. Can you just put in a 1/8 of a quart of fork oil or there about??? Or does it have to be exact 200mm from a test tube? Then it is 10 weight oil for front fork. Can you use any 10 weight oil like transmission ATF? Do you have to use motorcycle front fork oil? And then I don't know if I could buy the same brand of oil in the Laverda manual locally. I want to be sure about leaks...Evan
 
Earliest model SF2 had 35mm disc Ceriani forks. Won?t be hard to find. Agree with Jo it?s best to use any good quality dedicated fork oil. There are various ways to fill wrt quantity. The links should have info on that. Bloody hell - Vince has written tomes in here on setting up his suspenders!
 
35 mm forks use 35x47x7 seals iirc. Fork oil is less quantity than for 38mm, the correct measured quantity always ends up about half inch above top of the damper rod with the forks extended and all air bled put of the oil (lift sliders up and down until you don't hear any more air in the oil). Some people fill as much oil as possible and use measurement from top of fork tube with slider all the way up. Rear shocks, you have probably heard, new tech leaves the originals way behind.
