I need to adjust the rear suspension on my bike in order to take a passenger on a regular basis, but do not have an appropriate tool to make the adjustment. Can you send me a picture of the correct tool for the job pleasae and where could I purchase one? Regards, Mel Hazell

bottom of forks turn all the way in, then back out 12 clicks
top of fork - trail riding = all the way out then turn in 2 clicks, track riding = turn in 8 clicks
Rear spring needs to be adjusted so the tip of the rear fender drops 2.75" when sitting on it.
The top adjustment (compression valve) will be close to all the way out for trail and 5 to 8 clicks turned in for track.
The bottom adjustment meters how slow or fast the shock extends (rebound). Stand on something at peg height with one foot on the peg and the other on your stand and shove the bike down. Adjust the bottom (rebound) clicker to match the front of the bike so that both return to top at the same time.
This is a good starting point for any bike.
To fine tune your suspension it is always best to have a suspension tech watch you ride and make adjustments until the chassis of the bike stays flat while the suspension does its work. Usually take a tech 20 minutes to set the front and rear compression and rebound track-side!
If you take off the seat you will find the mono shock for it...I just did this today for my girlfriends bike...if you have a tool kit for the bike look for the tool that most resembles a hook, (the name of the tool escapes me). Also have a repair manual from Haynes helps too.
But, remember that when you are sitting on the bike and the suspension is compressed there is less slack in the chain, so don't tighten the chain too much. Tighten it until you have an inch and a half / 3-4cm of slack in the mid point of the chain between the front and rear sprockets.
Take the bike off its stand onto level ground and stand next to it. While holding your motorcycle upright, put one foot on the foot peg next to you and press hard on it. The front and rear of the bike should squash down and raise at the same rate. If not adjust rear damping compression and rebound to compensate
Now you have a comfortable bike with adequate suspension balance. Now let’s fine tune it a bit. Again there are no tricks to setting up your rear wheel suspension, you have to understand what causes your rear suspension to work. Since rebound occurs after compression we will deal with compression first.
i am guessing that you bought the bike secondhand,if so you will probably find that the preload on the front and rear suspension is set to hard,to adjust the rear(some bikes come with the wright tool,but not many)look to the top of the rear suspension shock you should see two locking nuts that go right around the shock,undo the top one(may need to use a large screwdriver and hammer)undo it till about 1/2 inch away from other nut then undo bottom nut and undo till it meets the other nut then sit on the bike and bounce your behind on the seat and see what it feels like it should be softer,repeat the sequence untill you get the suspension feeling the way you want(dont forget to screw the top nut down and lock it tight when you are done,the front forks should have an ajustment for preload,these are normally a simple screw in srew out adjustment,located on the top of each fork leg,screw in(to right) to stiffen up the suspension screw out(to left)to soften up i hope this helps,most ducatis have numerous adjustment for preload,rebound,and damping so what i would do is find a ducati dealer or some one who has a bike similar to yours and get them to run through the various settings and adjustments with you ,you will be surprised at the extent to which you can tune the bikes chassis and suspension to suit your riding style and even the types of road or race track you ride on,i can retune the suspension of my race bike as i have noted the settings for each track i race on and it is worth about 3seconds off my lap times...hope this helps
you need to use the shock adjustment tool that came with the bike and just stick it in the adjustment holes typically located about half way up the rear shocks and turn it to the proper tension for you
the rear shock is adjustable, the ring below the spring turns and locks onto a kind of peg on the body of the shock. being that your bike is an 86 it may even be time for new shocks or an upgrade to stiffer. if you do adjust then make sure both sides are on the same setting. as far as tools needed some shocks can be done by hand with help from someone lifting the weight up on the back end. i dont know what kind of tools as i cant find a good pic online of your bike but maybe a C spanner / wrench
