can you swap the coils front to rear for further testing ?
i dont care if you have been a mechanic for 10 years doing something for a long time does not make you good at it, take my gf for an example shes been walking for 28 years and still manages to fall over all the time.

QuoteHowie, dealer checked coils - say they are OK - but I fear this is intermittent and gets worse when hot.

Coils will do that.  You need to check them when the fault happens.  You can get a break in the winding that only opens up when the coil is hot.

There are no published specs since Ducati's method is use the DDS.  You could measure your known good coil as a spec.  Measure  the resistance across the small connectors and the resistance from the tower to the negative terminal.  Or do it the easier, faster way, swap spark plug wires from coil to coil.  If the miss switches cylinders you have a bad coil.  Check the ignition wires too.  There are resisters in them that can go bad.

Just thought I'd put the final result up here.

Turns out the bike had poorly adjusted valves, which led to compression issue, and then also badly adjusted throttle bodies.

The coil faults still show up, but the bike runs fine. I guess it's just one of those quirks. It's a Clayton's Fault - the fault you have when you're not really having a fault.

Cheers...
