Question about 2000 Moto Guzzi California Jackal
This is fuel injected bike, and usually runs fine, no problems. However, every once in awhile, it acts as though its having a fuel or electrical problem. It will suddenly start to lose power. If I apply more throttle, it will just start to choke and sputter and lose more power. If I pull over to the side of the road, with the clutch disengaged, I can rev up the engine, no problem. But, as soon as I try to put a load on it, it stalls again. If I shut the bike off, and let the bike sit, it will eventually start and run normally. I could go a hundred miles before it happens again, or it could happen in the next 30 miles. Today, it started out fine, but if I try to accelerate too quickly, it wants to shut down. If I accelerated gradually it got up to the speed I wanted and cruised along smoothly. If it had a carburetor, I'd say that the float wasn't adjusted properly, but its fuel injected. Any thoughts?
Just a thought as you asked...sounds like a poor throttle position potentiometer ... throttle cabled to butterfly most likely and if ECU dosen't know throttle plate moved you will see this symptom . If electric throttle , can you see(hear) plate moving whilst twisting , if so measure resistance/voltage on pot. . I do not know if resistance of position sensor can be measured while twisting throttle or pushing plate (bike off , battery disconnected or ignition off)

These are infamous for side stand switches that allow the bike to shut off and more importantly not start when side stand is down. Even worse is that it can activate even with side stand up. So either pull it off and short it out or clean up the connections.
