I Ride: 1993 Ducati 900 Superlight
Question 1973 Superlight Suddenly Loses Power

Correction: Should read "1993 Superlight Suddenly Loses Power"

After about a half hour into a ride, my bike suddenly lost power throughout the rpm range. Throttle response was very sluggish regardless of throttle position. The exhaust note was no longer "crisp". However, the bike ran smoothly with no misfires. Since this problem occurred instantly, I am a bit perplexed.

I might add that carbs were rebuilt, air filter re-oiled (K&N), sparkplugs & fuel filter changed & fuel tank cleaned recently. So I am confident that I can eliminate these causes.

I suppose that bad or dirty fuel might be the cause. But with no misfiring & the fact that the bike ran fine until the power loss occurred, I'm not confident that is the problem. Nevertheless, I will clean the sparkplugs & replace the fuel. If necessary, I will check the pilot jets since the power loss begins right from idle.

Any other suggestions would be most welcomed. Thank you so much.
