Shazaam’s Tech — Buying A Used

A useful technical article guest contributor Larry of San Diego CA (aka Shazaam!).


As any used motorcycle, your approach is to find a bike a well-documentated service history and the bike inspected by a Ducati-trained

A motorcycle that uses the oil to lubricate the engine and gearbox viscosity more quickly and needs oil changes more than an automobile. So look for a history showing use of a synthetic oil at 2,000 mile intervals.

The schedule is thoroughly covered in the and Service manuals that changed much over the The Owner’s Manuals for the 2000 to model year bikes are for download at:

Here are the questions you to ask the previous owner and your

Has the rear wheel spindle inspected?

1994-1998 models recalled so Ducati could for possible cracks present on the wheel spindle. The concern was this condition could the spindle to fail, causing a of control of the motorcycle and increasing the of a crash. Ducati sent inspection equipment to their who were authorized to replace if necessary.

Has the alternator wiring inspected and replaced?

The wiring and connectors between the alternator and the (on all model years) overheat they have to pass 30 amps continuously. The solution is to the wires with a larger and eliminate the in-line connectors. Do it you have problems. More

When was the last time the cam belts were replaced?

critical that the cam belts be every 12,000 miles to potentially catastrophic engine Ducati uses smaller pulleys that cause the to turn tighter corners the larger pulleys used in engines. Ducati also a small diameter back-side idler pulley arrangement causes the belt to flex in the opposite direction on each This back-and-forth belt promotes premature fatigue

The original drive belt often failed before the recommended 6,000 mile interval so Ducati now uses a fiber reinforced belt.

In particular, it will excessive back pressure to the pump which increases current demands thereby the charging system work which commonly leads to a failure.

When was the last time the filter was replaced?

A clogged filter causes the high fuel pump to draw higher currents that are contributors to regulator failures.

Has the to the starter motor been

The chrome plating on the rocker flake off and damage the cam lobes. A removal of the camshafts is mandatory to the full extent of the condition of the arms so ANY PURCHASE SHOULD BE ON AN ACCEPTABLE INSPECTION. Depending on the Ducati may elect to replace parts on out-of-warranty bikes but the will have to pay the labor

The following are some design and common problems that you also be aware of:

In-Line There’s been reports of developing at connections at in-line causing a high resistance to that overheats the wiring and holder causing a partial and/or loss of continuity.

Failure can cause bike to stop running warning. A clue is that the pump will not run when you on the ignition and toggle the handlebar to RUN. The 30A fuse (or 40A on later between the regulator/rectifier and the battery. can prevent charging and eventually the battery during a long

A clue is that the charge light (pre-1999 models) come on.

Internet Forums and Email

As you become familiar with bike and you spend some on the internet you’ll see many where someone asks for and gets incomplete and somewhat advice. You really don’t whether the response to your is from a real expert technical training, an experienced with suspension savvy, a guy who’s done it all, or a well-meaning guy just repeating he’s heard.

If it’s you’re after, internet speak volumes. It’s fun to watch or join the banter the best tires, spark motor oil, suspension air filters, and more. It’s the way to sort out complex issues and your experiences.

But, hard to sort-out opinion fact when your at a two or three sentence answer.

They offer-up knowledge and experience freely, but most people, they’re to offer extensive explanations to who doesn’t read the Owner’s or hesitates to spend the money on a manual, but want to pick brain with how-to type queries.

Performance Improvement

The performance boost to a Ducati from rider improvement. is truly awesome in stock so a riding school and track will pay huge dividends

A sure way to improve handling is to reduce weight. Ducatis are not as as current Japanese machines but reduction is easy albeit After you remove any extraneous (tool kit, reflectors, and have switched to a lightweight it then requires an expensive of magnesium wheels and swingarm, fairings, fuel tank, and nuts bolts etc. sky’s the limit here.) But care not to reduce weight at the of safety, reliability, and normal and inspection requirements. For example, too flywheel and clutch weight and you give up drivability and traction corners in order to gain

For increased acceleration it’s cheaper to increase horsepower it is to reduce weight. Every pounds of weight reduction is equal to one horsepower from a point-of view.

Higher pistons, increased displacement, system changes, port cams, valves, crank rods, and full exhaust all are effective ways to increase but pushed to the limit, engine and service costs suffer.

The is to try to build a balanced package on how you’ll really ride the — a hard thing to do for of us, myself included. Start off by sure that the stock is properly tuned and adjusted. often can make a stock much faster for very money.

Suspension Settings

Let me say it up The factory recommended suspension will give you the best handling. Period.

The factory won’t provide the most ride nor will they result in the fastest track because any set of suspension settings is a and the stock setup is no exception. The settings were developed by test riders to give the best handling characteristics the widest possible range of conditions, so they are not necessarily the settings for your favorite or your personal riding

Nevertheless there are some adjustments you may need to make. one point bears mentioning up It is important in any suspension work, to a record of the starting point and all changes to avoid later regarding the effects of each

Initial Setup

Ducati makes two versions of their Monoposto (single seat) have a softer rear in them as standard because are not capable of carrying two people. (two seat) models a stiffer spring installed to the bike to occasionally carry a when you temporarily increase the pre-load.

Ducati monopostos, as are set-up for a rider in the weight of 65-75 kg (143-165 lbs.) If weight (including gear) is outside this range, want to replace your with a more (or less) unit to allow you to adjust the correctly to suit your own If you’re heavy and you ride a you’ll probably still be OK but a on a biposto will definitely a softer spring.

If your with gear on the bike is 200 or more, even if you’ve set static pre-load properly, the spring probably isn’t enough to keep the rear end bottoming out unless you crank up the damping.

To pre-load the stock for this heavier weight need to compress it so much you’ve reduced its effective of motion. The higher pre-load for a heavier rider’s weight also cause the rear to more readily requiring you to rebound damping to slow it

Too much rear spring will also cause bike to ride higher in the A higher rear end (or lower will give the front a steeper angle. This results in a tendency of the bike to where the rear wheel traction first so the rear end loose.

The idea here is you need to let the spring (not the control the range of motion of the Too-stiff damping causes problems over bumpy surfaces. Handling is enhanced the dampers are set soft enough to the wheel movement, allowing the to track the bumps rather skip over them.

surfaces are smoother so higher and damping of a taut suspension are of a problem.

It’s important in beginning any suspension setup the spring pre-loads should be first (including correct of required spring rates.) also important to note all of this should be done any adjustment of damping rates, or head angle.

You need to set the front and rear sag amount for your own weight gear and a half tank of The way this is done is by measuring the change with you on the bike in the riding position, leaning with enough weight your hands on the handlebars to your riding at speed. See bike’s service manual for the for setting the bike’s spring and measuring sag.

Again, buy a or Ducati manual, you’ll it.

After setting the pre-load on the springs, you can then go on to adjust the rebound and compression damping.

if you make any sprocket changes, make sure you’ve the ride height by changing the of the tie-rod adjuster. On superbike any size changes to the final sprockets or chain length usually require an adjustment of the axle eccentric hub that, in affects your rear height and wheelbase — and handling.

Finally, you should avoid using suspension developed by other riders, motorcycle magazine test who commonly tweak each new suspension settings in an attempt to on factory settings, and then the results. These settings may be an improvement for one particular rider on one track but the factory settings are the best overall comfort-performance for the average rider on an average

For example, a review of a dozen tests of Ducati superbike and rebound damper settings that even though is a wide variation between their settings average-out to the recommended settings. So it looks Ducati knows its business.
