Hi, I have a problem with my bike; the engine does start but when I try to accelerate it just dies, This happens when it reaches 2k or 3k revs. help please:banghead:

If you back off the throttle after you get to the revs where it dies, does it keep running? Does it backfire once before it dies when it gets to that revs?

 

[Shellos]

When it hit that revs the engine goes off, doesn't backfire or anything.

Does the dash also go off? Is it a power-off issue or can you hit the initiation button and get it to come right back on?

How does your kickstand switch look? Is it loose?

Will it fire up again if you roll off the throttle or do you have to re-start it?

 

[Shellos]

This happens even when I have it in neutral, only the engine goes off, the dash remains on. I can get it back on, but the engine will die again when it hits 2k

I have to restart it

I'm going with the crank position sensor(CPS). There are shims between the sensor and the casing, possibly two, which set the gap. Try removing one to reduce the gap.

Why would it have come out of calibration?

It maybe a faulty CPS for sure, it happens.

I don't know why , just sharing experience dude. If I had a $ for every inexplicable thing Ducati's do i'd be a very rich man. I had a 999 motor do exactly this at 5000rpm, not 2000rpm, except mine backfired. Removed 1 shim...fixed. Certainly worth a look, it's free. My current Euro 998s will only run with NO SHIMS & i'm certainly not going to get into asking why coz it came from the factory with 2 shims.

 

[Shellos]

ok, and where is it located?

After said incident turn the key off, hold down the left button and turn the key on. Big EF1 will display. Any error codes will show on the lower part of the display.

Here.

I have no error codes, that is why I'm not sure what could be the issue

 

[widewalker]

You won't get any error codes because after the engine stops the error is reset so there is no error anymore, it will start.

But my question is… what changed to cause this condition? A little Italian didn't show up one night and mess up the height of the ignition sensor.

Which begs the question, has the OP ever seen the bike run right? If so… when was the last time it ran right?

The bike was running as usual, I didn't use it for a week, then, this happened. The only explanation could be that my mechanic replaced the water pump like a month ago, but after that the bike was running fine with no issue, until now.

Yea, ya just gotta go through the usual stuff, battery, charging system, connectors first. I doubt something magically failed, its probably something loose or WET. These bikes don't like to get wet and any dampness can damage the fuel in the bike (condensation) AND connectors.

Ahh...the rest of the story. It makes even more sense now. Removing and replacing the left side cover can upset the CPS gap. The symptoms are consistent with this being the culprit, but not for certain.

 

[Shellos]

I have already ordered a new CPS, just in case, is there anything else I need to check when I replace it?
