In the event that I have to replace the ignition coils on my 1993 Ducati 900 Superlight, I am looking at a replacement kit sold by Ca-Cycleworks....
You are correct. The rear cylinder has always been the one that breaks down. However, when I switched the 2 wires from the pickups to the...
Well, it's time for an update (I have been out of town for awhile). I repaired the crimped wire (as noted above). Also, I reversed the wires from...
OK, today I followed Chris' suggestion & checked the resistance on the 2 wires coming from each ignition pickup. Readings were as follows: front...
Indeed!! Thank you!
Chris: I suspect that heat is the issue here since the sudden shutdown of the rear cylinder seems to only occur when the engine is hot & under a...
Derek: Your recommendation is very logical. My only reservation in following that procedure is that by limping home on one cylinder & am a tad...
Thank you, Chris & laava. Your thoughts are indeed logical. I will direct my attention to the ignition pickups. Admittedly, I have experienced...
Here is an update. After (1) replacing the fuel in the tank, (2) checking the fuel lines in the tank & to the carbs, (3) checking the fuel tank...

Thanks, Keith. The NGK caps seem like a logical choice.
Immediately after the crankcase oil became contaminated with fuel, I emptied the contaminated oil, refilled with new oil, ran the engine just...
In light of all the discussion we have had on my "loss-of-power" issue, I failed to mention something that might bear some relevance. Earlier in...
Thank you, Keith. I'll get to the bottom of this. Since engine diagnosis isn't my "day job" so to speak, it will take me a bit longer and...I'm...
Several months ago I rebuilt the carbs since I suspected that the floats were sticking. Although I did not remove the emulsion tubes, I thoroughly...
Yes, the throttle was held wide open.
Forgot to mention that I did exactly that. With oil in cylinders, readings were: front -- 119 psi & rear -- 114 psi. That tells me that there is...
Compression check indicates the following: front -- 111 psi & rear -- 109 psi. Considering that my compression gauge is of the auto-parts store...
The plug appears to be fuel-fouled. No apparent exhaust smoke with loss of power. I planned to check the compression, but need to get a different...
Both exhaust headers were VERY HOT.
