    Default Guzzi Rear Shock Dismantling

    As the shocks on my Lemon look very manky, I decided to remove the springs, see if the dampers still worked, and either paint them or order some new ones.Not having any spring compressors I used the tried and tested ratchet strap method. This worked pretty well, and I soon had them both off.

    Now that they are off, they both seem to provide minimal compression damping, but very strong rebound damping. Not having done this before, I'm not sure if this is good or bad, and googling hasn't helped. Can't test it on the road, as the bike is still in a thousand bits. My gut feeling is that compression is the job of the spring, and the shocks are therefore ok as they are providing strong damping on the rebound stroke, but before I paint them I'd like to be sure. Any ideas?

    That sounds correct, you don't really need a lot of compression damping (why would you want to slow down the suspensions upward stroke?) but if you have no rebound damping you get a pogo stick.

    Agree with JB. Sounds like a lot of rear end work going on with Guzzis at the moment. But yes, springs compress, the dampeners damper the spring back .

    I always thought you should have equal damping both ways ?

    Right you are, I'll paint them and see how they go. They can always be replaced later.

    Thanks chaps!

    You sort of do. You have the spring which works in compression can be wound differently (tighter) to give a different compression rate. On my old S&W shocks there are two different springs which are wound different with the red springs being much tighter. See picture below. On more fancy suspension rather than old tractors you can have fancy compression (fluid) based compression damping but on a Guzzi anything more fancy than Fusilli pasta springs is the devils work.

    Nope, always more rebound damping, a lot of old bikes have no or very little compression damping, but most of them don't have enough power to compress the rear suspension which is generally when you need compression damping.
