I've travelled a lot around Italy and Europe in the past, and now I have a problem on the forks: they're very soft and the right one is leaking oil.
Do you know the exact procedure to change the forks oil and the fork seals on this lovely motorbike please?
Maybe with some pictures step by step and/or a video?
I will be really appreciate!
Thank you!

Hello and welcome to the Forum
Yes, a Polish friend of mine, also has given his Morini a name. In the Netherlands that is not usal.
The procedure to change the fork oil should be in the owners manual.
What you do is take a bowl to catch the used/old oil and put it below a forkleg. Undo the small bolt at the bottom of the forkleg. Then push the bike down a number of time to "pump" out the oil. Then do the other side.
Put back the bolts and open the fork at the top with a special tool. Poor-in the requested amout of oil (300cc?? per leg). Make sure to use the correct thickness of oil. In the late 78-82 350 Sport/Strada models,
30 W is a very good thickness of oil. In my own 1973 Strada, I use much thinner oil (10 W or 15 W, not sure). Have a look if you find the thickness in the owners manual.
To renew the seals, you have to take the fork legs out of the top and bottom yoke. With a screw driver you can pull-out both seals per leg. Each leg has got 2 seals. Go to a shop where they sell bearings. There you can buy the correct size seals. Get 4.
Best way to operate:
1) empty the legs (take out the oil);
2) take out each leg to replace the seals. Clean the inside of each leg while doing the job;
3) check the inside legs of damage from small stones and also check if the inside legs are straight by rotating them on a piece of glass;
4) push in 2 seals per leg;
5) place the legs back into the jokes and secure them with the bolts in the top and bottom yoke;
6) fill each leg with new oil;
7) ready.
I have no pictures, but our Club has a manual in Italian/English on the Marzocchi fork, showing all the steps with drawings.
Hope this helps.
