   This a old mod . If you have the Factory Maico Information Bulletins you will find this Mod.


   Try 10 wt oil.  Use Ariete Fork SEALS. Must Have a good Pressure Gauge. NOT a Tyre Gauge.

Nebo, with standard 81 490gs forks, what oil and pressure is a good base setting?

   Start at 1/2 Bar or 7 psi . Do not exceed 14 psi or 1 Bar . Standard Oil amount and Level

   Is per Manual.

 
   
    Fork springs may have sagged. Make some 20 mm spacers from Alloy or High Impact Plastic .

    Or Chippys Maico has new Ones.   I think .47kg are standard. Heavy are .49kg. Will check.

      Skill level and rider Weight is a big consideration.
