Most of that kind problems are connected to fuel/ignition system, thats why. Read close topic "problem with idling". U have changed/checked near all other possible things, so Injection should check next! Remember, that there are also "not so good" Ducati dealers, who cant find solution to problem, but surely they can take Your moneys easily.... Ps, Injection NEEDS, that Your battery is filled with current and it can also give it to system = Good battery and NOT clogged fuel filter are "MUST" in injected bikes !!! :thumbup: |

My guess is it's the exhaust and if you check for leaks at the muffler/pipe junction, you'll find one... if not there check at the crossover and then head. Wildcard guess - all of the little plugs are still in the pipes, right? If the bike's backfiring through the intake you probably have an issue with the mixture. The "Euro chip" probably isn't enough to compensate for the modified airbox and mufflers - you really need an aftermarket chip to keep the bike from running lean. Too lean and you can burn valves... |

70 degrees and sunny eh? Well in the UK it's 41 degrees (F) and a bitterly cold North Easterly is blowing down into South Wales. Too cold for 907's today - I'll take the car. Hope the problem is solved, mine is chipped and goes well with open pipes.... |

Remember to check also COMPRESSION in both sylinders !!!! If its exhaust valve problem, then easy to check with compression test. :thumbup: |
