"the pilot jets need to be cleaned AGAIN"
I'd go so far as to add the phrase "and full fuel circuits" to your comment above.
Something additional is wrong as this has become a repetitive situation.
My carbed 900SS Ducati starts/runs/accelerates perfectly after a recent 6 week "vacation", recently documented and linked right here on ninjette.com.
