Hesitating, coughing, sputtering at full throttle.  1100 miles total, 500 miles since service. Tank is half full.
Rides well, it seems, at half throttle, but sputters when wide open.
What's going on? must be the carbs
Any ideas of simple things I should check before I bring it to the shop?

thanks

Sounds like you better "pilot" your RE and "jet" to the shop!

Bad gas? a little waterr in the tank? Simple stuff first

Do you hear the fuel pump spin up when you turn the key and flip the switch?

 Also check your plug and wire. The throttle body and air filter connections,all intake connections.Throttle body to the head. Make sure air is not getting sucked in anywhere except through the filter.If when you pull your plug, it's all white, that could be a sign of the above, running too lean. you could also try spraying some carb cleaner, wire contact cleaner or wd-40 around the intake connections, your listening for a change in Idle.Make sure the air filter is OK. I know, you just had the serviced, but check it, what the heck.
  It does sound fuel starved to me though.Check inside your tank and make sure you don't see anything floating around, or laying at the bottom of the tank, that could be getting into the fuel line.It also could be a sensor. check all the wire connections to the sensors, Is your engine light glowing? If it is, there a test wire that you ground to the chassis, it will make the engine light blink whatever trouble code there may be. It will be a series of blinks, and depending on what the series is, it will tell you whats wrong.
 Maybe also check the head pipe on the exhaust, make sure it's tight. If loose, it maybe screwing up the O2 sensor?

Fuel pump whirzz. Air filter looks and feels normal.
Plug, will see tomorrow.
BTW the last 500 miles were all in nice, dry weather. Also she has a reverse cone pipe.

I had warmed her for 10 miles or so and was trying if REALLY, I couldn't get her to go over 100.  Mm, at least 10 short. Then returning home, she started sputtering, like a runner who had pulled a muscle.
So sad, I thought that is what those bikes are made for: hugging the tank, nose in the clocks, feet on the passenger pegs, left hand holding the forkleg, right claw in a throttle cramp...

Oh well, will see if she is the same genotype and constitution as scooterbob's

cheers

Took mine to top speed around 1500 miles, no problems so don't worry too much.  Didn't make much over 80 but I'm fat. 

Spark plug wire on tight?  Check for other loose electrical connections.

 Oh, why didn't you say that in the beginning? You blew the motor LOL!

[Ducati Scotty]

Hey, have some sympathy gorilla.  Poor guy's asking for help.

If you really blew the motor it prolly would have quit at speed, not on the cruise home.  Though it is suspect that it started right after your high speed run.  Start checking for loose electrical connections, frayed wires, etc.  Don't be afraid to stop at your dealer and be honest.

 OK , just kidding

[SSR]

I feel its the plugs. Check them if they are shot or need gap adjusting.

[Ducati Scotty]

OK , just kidding

No! Unacceptable!  This has gone too far!

I delcare no more messing with new owners until 2000 miles.  They are young, fragile, vulnerable, and need the utmost protection from web site hooligans like YOU gorilla!


  Totally kidding.  Just trying to help newbies along without too much harrassment, that's all.  If you have the undeniable urge to hassle someone pick me.  You can razz me all you like, I can take it.  (I hope.)

Yah, gotta' be a little bit careful with the new fella's.  After a several months hangin' out with you guys I have sorta' figured out your personalities.  But a new guy with a problem is under enough stress as it is.   He might have laid down his very last 6 grand for one of these and not understand that they are not the latest in manufacturing technology.  Add to that a young wife that my not be fully on board and a kid....well, we have all been there before......

We want them to stick around for a while....besides we need the fun!

It will be something simple. The odds of "blowing up" that engine are about zero unless you run it with no oil. It has a rev. limiter to protect you from yourself and the engine is very well designed.

I also suggest taking into the shop for some warranty work.

[Ducati Scotty]

When the US distributor has your back on warranty work, you can't ask for more than that
