Question about 1998 Ducati 900 SS
The bike starts perfectly, runs good until it gets hot, then it starts to miss fire and stutters at 5000rpm, what else can i do?
I have to have you start at the basics first on this one. Check the spark plugs, the plug wires, and most importantly, the timing belt tension. Check all connections going to the crank sensor, and also check the rectifier connections and the coil pack connections as well as the spark boxes. Also, when was the last valve adjustment/belt replacement? Usualy the injected Duc's don't ever pick up missfire conditions. The Carburated versions are sometimes known for it, but usualy it's the result of the carbs out of synchronization. I would be willing to say this is a tune up issue rather than a broken part issue. If it were a broken part, you'd be experiencing the issue almost all the time, not just at high rpm's and high load. Check the tune up, let me know if anything looks out of the ordinary in there.
