Bevel twin ignition (900 SSD)

I’d welcome any suggestions/recommendations on bevel twin ignition. The Forum seems to have been quiet on this topic for 3 years. My 900 SSD has eaten one or two Bosch ignition boxes in the past (and the regulator/rectifier went a few years ago, complete with melted wiring.) After a few problems with the Bosch boxes last year it ran fine all summer after cleaning all connectors.

Now moved up to Perth, so I’ve left my old network behind. This spring the engine fired up fine on one cylinder (Front), but lots of backfiring on the other (Rear), and on a test run no life from Rear cyl at all. Investigated: No spark on Rear cylinder, okay on Front. Swapped all components over to trace fault, reconnected and now getting sparks on both plugs, but engine will not start at all, occasional backfire. Newish battery, fully charged.

Odd resistance readings on Pickup connectors: 70 Ohms (Rear) and 0 Ohms (Front) Should be 220 Ohms. Note it was the FRONT cylinder that was working, and both plugs were sparking after reassembly, but perhaps not at quite the right time??

Pickups and/or pickup wiring seems to be a known problem. Maybe that was causing the problems that mysteriously resolved themselves last year (I’ll be honest - I haven’t had the LH engine cover off yet to poke the pickup wiring.) Has anyone successfully replaced the pickup wires, if so where do you get oil/heat resistant wire?

A few questions:

  1. How do I know for sure what is working and what is suspect - what’s my logical path into this?
  2. Should I assume pickup wiring is the problem and just replace that. I see Bevel Heaven in the US have a kit for just the pickup wiring replacement … SS-Darmah/
  3. Would I be better off replacing the whole ignition system. Silent-Hektik have a replacement kit comprising pickups on a mounting plate, rotor, 2 coils, 1 ignition box: Anybody tried this?
    (Mdina Italia seem to be fresh out of most OE and replacement ignition components)
  4. Is a Ducati dealer (Glasgow Ducati - 60 miles, is my nearest, they say they’re happy to look at it but not until September) going to be able to deal with this or am I going to have to go it alone? I can’t find any local bike specialist in Perthshire at all (nor even a club branch!)

Thanks, Dave

Hello Dave.
The first place to look is the pickups, the original wiring was never rated for use in oil, sso it eventually turns to slime and sorts out so no signals form the pickups.
Andy at Mdina Italia does a service exchange on these, or Electrex World do them.
You will need to have them set up when replacing in the casing.
