I've been finding out alot of information about the Ducati 916's, advantages, disadvantages, do's and dont's.

I've come across the electrics. Post 1996 they use Bosch electrics I believe as they have problems pre 1996 with cutting out etc.

Should I not get a pre 96 because of the electrics or are they really not that bad? Can be fixed, not a problem now etc?

Thanks

Jeff

No, turn it down because of its engine! Laughing There's a good buyers guide feature in motorcycle mechanics,it might be an idea to get a back copy of that. I personally haven't had any experience of Ducati so i cannot possibly comment........... But if that's what you want then don't be put off by tales of high maintenance.
I would guess that any pre '96 models may have had their electrics updated now.

The problem was just the wiring from the flywheel to the regulator, wire was too thin and the reg was also in the wrong place and tended to get too hot. This caused the wires to burn out.

A silly problem really, but VERY easy to fix.

All other electrics are fine, there isn't really a great deal to the electrics on that year 916. Its all very simple. It was just the reg wiring.

Thumbs Up

Barry you are a diamond.

Thanks for letting me know, I'm getting to know more and more about them now.

I'm glad you cleared it up for me Thumbs Up

Obviously this problem has been around for over 10 years so I was guessing there is a kit you can buy maybe?

Thicker wires? Aftermarket regulator?

Thanks

Jeff

Bingo! Thats all it needs, job done.

The regulator is located under the battery tray on the right side of the bike. On the very early ones there was no air vent to it so it tended to overheat and burn the wiring out.

Ducati revised this by cutting a small vent into the fairing to get some air to it, but for some reason done nothing about the wiring!!

They must have just thought that making the reg cooler was enough!?

I found the 916 a piece of p!ss to work on, I had both cam belts replaced in under an hour. There really is nothing to them.

Thumbs Up

There is a plastic connector between the alternator and the rectifier, this gets damp, goes high resistance and then burns out leaving you stranded with a flat battery. I cut mine out and soldered the wires together, some people use bullet connectors.

Other issues (much bigger in my opinion) are rockers, crank gallery plugs backing out and cush drive popping out and machining away the rear hub.

Rockers were more a problem on the higher rev'ing 748.

Thats another Ducati myth i'm afraid. All pre testastretta four valve engines suffer from rocker problems, my ST4 (with the 916 engine) has had four rockers so far, my mate with his 996 needed 12 (!!) plus a cam shaft!!
The only way to check is to pull the cam shafts out and take each rocker out and look at it.

If we didn't buy bikes everytime someone said it has a known problem we'd all have cg125's. Like it, buy it, fix it, crash it, get something else then do it again. Laughing

But there is also a major known problem with CG125's, they are slow. Laughing
