I had an 860GT for several years and many kilometres. Its true that the switchgear is rubbish, I replaced mine with a Suzuki item. The voltage regulators are poor, but this is a common problem for most of the bevel twins and is easily replaced. They are hard to start but a two-into-one exhaust syste...

Sammy Miller Ducati Crash - 2008 TT Races

Evidently Sammy was able to walk away despite the superman imitation.

Looks perfect! I had a blue one that I greatly enjoyed. A much underrated bike. I think the style, which wasn't much appreciated at the time, has actually aged well and makes it a really unique machine. I had to sell mine when I moved across Canada but made up for it by buying a 900SS. Bruce Martin

I'll second Craig's advice. I've often found that simply lubing the cable(s) or straightening out the runs will cure the hanging idle problem. You should be able to hear the thottle slides banging smartly onto the throttle stop screws, and they should be doing it simultaneously.

I use the following method to set up the carbs: 1. make sure that there is plenty of slack in each throttle cable; 2. start and warm up the bike; 3. either turn in or out the throttle stop screw in each carb until you get a balanced idle. You can tell that this has been achieved when slight turns ou...

One more thought. If you have the 40 mm carbs, the tickler can jam the float down. Repeated use gouges a small depression in the float which causes it to hang up on the tickler plunger. In my case it made the bike almost impossible to start but I suppose it could create a situation in which the bike...

I have had a leaky float do this. Check for fuel sloshing around inside the float. I presume the throttle slides are correctly synchronized. Another option is to make sure you are getting a good spark in that cylinder at low revs. An intermittant contact on one of the thin wires leading from the ign...

Make sure all the indicator bulbs are the same voltage and wattage. The flasher relay normally uses the bulbs to determine the flashing rate.
The fact that the bulbs illuminate means that you have power going to them and that they are properly grounded.

Don't bother replying - not that anyone did- I found a wiring diagram from a late model 900 GTS that provided the information I needed. With that and some circuit testing everything now works as it should.

900SS Turn Signals

I'm restoring the function of the indicators on my 1979 Bosch ignition 900SS so I can get it through a motor vehicle inspection and would like confirmation of the wiring to them. Do the blue/black and blue wires connect to the signal flasher? There is also an azure/black wire in approximately the sa...

I had one of these for years. They are good, solid, greatly underrated machines. The best modification I made was to switch to a lower restriction exhaust, in my case a 2-into-1 that I purchased in England. It greatly increased power, flexibility and made it much easier to start. The 860s were notor...

Have you tried checking the timing with a strobe light to see if the timing changes as the bike is revved? The Bosch units may not be advancing the ignition timing properly hence the overheating. I am not an expert but I would think if the bike starts and runs the ignition generators should be fine....
